I agree. Uncle Chuck, despite his whole kind demeanor towards Ian & Edwin, is a bad influence in regarding Ian.
At least with Edwin (MC), he has his whole career in becoming a Doctor where he can fall back to, even if he should for some reason turn down the whole Carnations club managing job by the end of the game.
Though while it's easy to say "MC should steer Ian away from uncle Chuck's influence." putting it into action I feel is incredibly difficult (I mean, from what we've seen of Ian so far, he really loves his job at the Carnations Club, so is getting him away from there and back into school [like what his mom seemed to suggest] even a possibility? Hmmmm
)
