Hmmm, that is an odd one. I haven't tried out the co-op yet, just finished my first playthrough and am trying to convince my friends to buy it.
My party was Lohse (me), Red Prince, Sebille, Ifan.
When it came to Roost both wanted to chat but Sebille took priority, in both cases I fiddled with a fight broke out. I killed Roost after Sebille's dialouge and then decided to soldier on.
When I bumped into Alexander at the Nameless Isle, Ifan's quest seemed to catchup and there was some stuff between Ifan and Alexander.
Later on, when it came to the Prince of the House of Shadows, Sebille had her dialouge, killed the Lizard, then used Spirit Vision and was able to chat with the Red Prince.
