I never thought about that! Which I should've done because I'd often switch between my two main characters in D:OS depending on the situation (in fact I'd often do the same in Dragon Age, now that I think about it: it was fun playing through bits of Origins as Dog). It also makes sense to play as Mr Deathknight as he has a significantly better carrying capacity to lug around all the stuff I want to sell.
I also realised while reading through the timeline that I totally forgot about Dragon Commander again. Shame I can't play as a female character in that one, though they all seem to end up being referred to as their male counterpart by the game's lore anyway...
