Is there a way to chose which character evolves in coop?

[storyteller83]

My coop-party has come to the point in the beginning of act 3 where you can evolve. for unknown reasons it gave the whole dialogue to the bard in our party who under no circumstances wants to do that, while the party member who is absolutely itching to, cant. we have tried reloading, moving away from the emperor, starting the fight in different ways, nothing. we are about to give up on this game. this seems like such a design flaw in the gameplay. can you simply not control who gets to make that choice? i understand that the other players can later on decide to ALSO evolve, but that is not the solution.
please help. we are about to stop playing.

Bard says no->Emperor gives the tadpole anyway->Other characters use it

When I was making choices in that conversation, I said I wanted to evolve and it presented me the evolution worm, then in the same convo after it shown me the worm, i had the next dialogue choice one of them saying i need to think about so, I said I need more time to think about it. Now when I talk to the people in my camp, there is a option to talk them into taking the evolution worm.
