So, because security at this place is REALLY half-assed, somehow Sam and Dean casually go to the morgue and start examining the body. Don't they even have security cameras around? Sam finds a puncture wound in the neck. He sticks a Q-tip in there and it goes all the way into his skull. Eww. Notice how when Sam sticks that Q-tip in there it comes with squishy sound effects. Somehow, neither Winchester is squicked out by this. Sam sees a bone saw nearby and wants to prod more. So, Dean gets to keep watch. Cue to Dean who only has to hear the sound of the bone saw crunching and he gets queasy. Sam, who's FINALLY over his sickness of blood and gore with bodies, skillfully carves off a perfect cap of the skull. The brain is black and shriveled. Eww. 

Dean hears someone coming. He goes into warn Sam, who's holding a shriveled brain in his hand. While the nurse walks down the hall, Sam calmly puts the skull back on and they get the body back in the drawer. Sam dispenses of the bloody gloves with a nice toss in the trash can a split second before nurse perky walks in. Except she's not very perky. She's thinking they shouldn't be there. Good conclusion! Unable to come up with an excuse, Dean goes and does something that will NEVER EVER have fans think about a popular dessert the same way again. 

Dean drops his pants, showing off the bare legs but nothing else, and he holds his hands up in the air. "Pudding!" he shouts while shaking all around. Damn you CW! You know a full frontal would have gotten you ratings. FCC fines too, but hey, publicity is publicity. No such luck. He pulls his pants back up after the nurse laughs. She'll give them a pass and take them back to their rooms. He goes back to Sam and tells him crazy works, but Sam is way too bothered. I would be if my brother did that in front of me!

Next are drawing of creepy clowns on the wall. Dean jokes if they're original Gacy's. Again, for all you young folks, John Wayne Gacy was a serial killer of young boys in the 70's. His MO? He was a clown. He was known in prison for his eerie clown paintings. So, Martin says, "I painted those." Oops! Sam breaks the awkwardness and gets to the point. What sort of creature sucks brain's dry like that. Martin has a theory and it's scaring the crap out of him. It's a wraith! They crack open skulls and feed on brain juice. Eww. How do they kill it? Silver. Man, considering all these creatures can be killed by silver, I should be keeping some around all the time. However, the catch, which is true of other creatures as well, they can be disguised as humans and spotted in a mirror. It could be anyone. I'm betting that way too perky nurse.  

Sam, whose obviously not thinking, wonders why it's in a mental hospital. Duh, who's going to believe a nut claiming they saw a monster? It's the perfect hunting ground. I worked in a mental health office once. I can honestly tell you, most of the staff were just as nutty if not nuttier than the patients. I think because they live in a state of denial. There's no such thing as monsters my ass. I once asked a friend, deeply struggling with some personal issues, why he became a psychologist. He wanted to prove to himself he wasn't nuts. Psychology can justify anything! (Ignore this Jas, you're just fine!) 

Anyway, Dean is standing by the nurse's station watching people walk by in a mirror. Hot therapist shows up wanting to know what Dean's doing. Dean, in perfectly honest mode, says he's hunting a wraith. She theorizes she could be a monster, but Dean tells her she passes the mirror test. Oh yeah, that sounds so half baked. Therapist goes for more questions. Why does he have to hunt monsters? Why not let someone else do it? "Can't find anybody else that dumb." Sure you can. He's your brother. Dean goes on, pointing out someone has to save people. She asks how many people he has to save. Wow, she's not letting up, is she? Dean gives the answer that we aren't surprised over, but still we wonder how he hasn't gone howling by now.  "All of 'em." 

She's surprised by that and asks him how. Dean doesn't have an answer. She tries again so he tells her. "It's the end of the world, okay? It's a damned biblical apocalypse. And if I don't stop it and save everyone then no one will and we all die." Man, is he setting himself up for a huge failure. She mentions that's horrible. Apocalypse or no apocalypse, monsters or no monsters, that's a crushing weight to have on your shoulders. To feel like six billion lives depend on you? God, how do you get up in the morning?" Dean has no answer other than that's a good question.   The whole conversation is interrupted when that arrogant bastard, I mean the doctor, says hello to only Eddie (there's a clue!). Dean sees a wraith in his reflection. Ruh-ro!

Sam comes over to Dean and Martin in the hall with three silver plated letter openers. He had to raid three nurses stations. How did he get away with that?  He's so big and pretty, how was he not noticed? Plus, there's that not working security camera issue again.   Their fun is interrupted by Wendy, who shoves her tongue down Sam's throat. He seems to be a little less willing that Dean was. He doesn't kiss back. Oh come on Sammy, lighten up! "I want him now," she says lustfully. "He's larger." Okay, who's teasing the fan girls here! Stop it! Dean shrugs. "You've had worse." Ooh, banzai! Sam only has a bitch face in response and gets back to the case. 

They'll have to get the doc after lights out. Martin protests. He can't do this anymore. I'm certain that's why he called Sam and Dean to begin with. Dean pleads the security will be tight (?????) and they could use the backup. Martin protests. So, how do they convince him? By mentioning Albuquerque?   Oh, good job guys. It doesn't work. He mentions he thought he was invincible once but he was wrong. "Why do you think I checked myself into the Hotel California?" He runs off crying like a little girl. 

Sam and Dean check the office, no arrogant bastard, I mean doctor there. So they separate. This isn't going to go well, I know it. Sam spots the doctor first and hides with the blade sticking straight out. This of course triggers a memory from a weapons discussion I had recent with my Taekwondo Master, so I'll take a few seconds to educate you all. If Sam was holding a regular knife with sharp edges and is a true trained expert, he wouldn't hold the blade like that. He would conceal it by holding it along the forearm pointing up. That way when he attacks he can go straight for the throat. However, this is a letter opener with only a sharp point. It's not an effective weapon for killing because he has to hold it pointing straight out like he does. That creates less opportunity for the blunt and swift strike. That's why when he does attack, he gets the forearm instead and only wounds. Interesting huh? 

The doctor leans backward and Sam takes another swipe in the air, missing. The two orderlies jump him right away and knock the silver letter opener out of his hands. They try to drag Sam away, but Sam punches those two, throws one through a window. Ruh-roh. What is of importance here is Sam is raging big time, exactly like he did when going off on those two hunters in "Free To Be You and Me." He looks freaking scary. After taking out the orderlies he picks up the letter opener, chases the doctor down the hall, tackles him and goes for the kill. As he brings his hand back Martin stops him, pointing out to an out of his head Sam that the arm isn't sizzling. It's not the wraith. Sam comes out of his rage mortified, totally distressed over the idea that he almost killed another innocent. Not good for an already majorly messed up psyche.
