Thank you for letting us into your mind.
Good to know you're as conflicted as I am.
My viewing of Nathan goes back to his days as Joey on OLTL,
and while I've always enjoyed his performances (and despite the fact that he now is a bit pudgier than works for him...it's never a good thing to be able to do a good impression of Fat Elvis )
he unfortunately will never be able to out do DB who is just a delicious actor in all variables.
Sticking with the characters - Booth would kick Castle's butt any day to boot.
Booth has never lied to Bones - not even to save her pain, and I am not looking forward to the fall out between Beckett & Castle when the lies all come to light as they inevitably will.
