Hey, Gorse was perfectly capable of keeping something a secret as long as you like... told him it was a secret.

... And as long as no one directly asked him about it.

He kinda can't lie worth a damn, his face is too honest.

"Oh, sure, that's the idea innit? I wanted to see the world or at least more than the same few miles I grew up in. Inquisition seemed like a good opportunity for that, an' I get to help people while I'm at it." What wasn't to love about that? Two birds, one stone, as the saying goes.
