Grey's Anatomy Season 1 Episode 7

I'm currently on season 1 episode 7 of Grey's Anatomy and this episode is insane but there is one character that really has me going "wtf", Digby. What is wrong with this dude?

I mean, this dude is a total masochist. At first I thought the worst thing he could do was getting himself shot but no! This guy wants to be awake while his long is being drained of blood and during his surgery?! That is a whole other level of wtf!
