There is a 4 hunter dropship conversation when cabot goes through the mission, what they are doing and the risks. Each of the hunters talk in this one. So maybe both abes can talk in this.
I doubt it. Pretty sure none of the adaptations with custom dialogue are in that conversation.
yes but they cant talk at the same time or not at all
That line of dialogue will not play because Renegade is on the team. If any other Assault was on the team it has a chance but because of Renegade there is a 0% chance of that happening. Abe only has dialogue for when he is in the Trapper role and Renegade is an Assault. Additionally Renegade has no extra/custom lines of dialogue.
So no; this wouldn’t work.
