There are possible logical explanations for Tav to be selected as leader, I had mentioned one - she/he just has the better parasite. Like an alpha parasite. or maybe its like the Nameless One Planescape: Torment - he attracts people like himself, who exist in opposition to their natures. All of us having the parasite draws us together, and we subconsciously select a leader.
Sure. That would be a great story for them to actually tell in the game.
[Illithid][Wisdom]Use your connection with Wyll to force him to back down.
As Wyll draws his blade to settle the score with the goblin that took his eye, his hand trembles with the sword half drawn. He glares at you in recognition, struggling against the invisible force of your will. You hold his gaze until he looks away, defeated, and his blade returns reluctantly to its sheath.Using the tadpole to dominate your companions into submission would be a great explanation for Tav calling the shots. Unfortunately, such an explanation is not currently present in the game. Nor is any other explanation.
