I'd like to see more of T, but with a s/l that is more than playing sidekick to WilSon. He does seem to like Gabi, but she's so mixed up that I don't think that would work very well at least not right now--and she is leaving, anyway.
As for making Sonny's club more youth-oriented, that's not such a bad idea, but it IS a drinking establishment, isn't it--not a teen "coffee house? I don't think it would be so great for business if it became more of a youth hang-out, which might keep some older potential customers away. And Sonny needs the club to be not just "fun" but financially successful, since it looks like it is the main source of income for the Will-Sonny-Gabi-Ari family.
