I don't normally like quiet, stoic types but something about Lee has always touched me.
Maybe because he has those (quite frequent) moments where his stoicism erupts and he loses it? Either verbally or in a self-destructive way. I think the pissy bitch aspect of his personality offsets the stoic quite well really. ;) Makes him way more human in my eyes! Something about the way Jamie plays Lee emoting means he doesn't feel closed off as such characters often would to me.

Lee and Kara need to argue and frak and fight forever and ever and ever, amen.
