Depends on your definition of "good". I will have to kill you but apart from that you're fine.
Blackwall locks in on the battlements in Skyhold.
Cullen locks in when you speak about starting a relationship, pretty hard to miss.
Solas locks in after his balcony scene ("...but losing you would...." *kiss*)
Bull... I dunno. After the sex scene I think but I only ran through till I got the necklace (without checking our status) and broke up then.
Josie also after you speak about starting a relationship.
Sera, dito.
The others I don't know.
Okay. I'm still good then. I haven't discussed 'our relationship' with Cullen. Just about to head off to do Solas's quest and then the kissing is after that, so as long as I avoid any more romantic options with Cullen, I should be alright. Whew.
Cullen will get his turn. Just not with this Quizzy. This one is for Solas. The next one will be female/mage/human. That one is for Cullen. Assuming I play a next one. I will. Maybe not soon, but I will.
Edit: it would be only fair, though. Since Solas stole my first elf Quizzy away from Cullen. But life isn't fair. And this is canon. IF it weren't the canon run, it wouldn't matter.
