I'm actually wondering if I should've made Carver a Templar now, on the off chance that he'll be with Cullen's little military faction safely away from the red templars and the rebel templars. Mind you, I made him a Warden, so hopefully he'll still be hanging around with Alistair (and my Warden). Tbh, if he's with any of those 3, or my Hawke then I know he'll be just fine.
GAH. I'm wondering that myself. My planned run (I am actually, um, playing my DAO canon as I type this) has him as a Grey Warden, because it makes him happier, but...
