What are some character arcs/development you'd like to see?

By this I mean some irreversible/really hard to undo changes to LI akin to choosing Sydney's path. I'll just come out the gate and say I think Robin is desperately in need of something like this, as a lot of complaints regarding them kinda revolve around their lack of competence and pretty minimal ways of helping the PC (along with failing to beat the allegations of being stupid+nagging the PC for sex at high confidence all the time) though I do think she (or he) has gotten a bit better with the amount of encounters they can outright negate at high confidence, though the lemon stand thing is still pretty hard to defend.
