Yes, I guess that each story arc would be pretty different in scope and now that you've asked us to break it down like that and I've actually thought about it, I guess Gwen's could really be done in one hit as well.

Basically, she'd reach 'fully healed' status and reveal to herself and others whether she is or is not human and then the aftermath of that revelation would pretty much happen immediately. Either she'd make a play to reclaim her father's estate or ...not, if it turns out she's actually just a program.

I guess I just imagined her step mother's goons showing up and attacking her directly or hacking attempts affecting her actions in battle and stuff and didn't want those scenes to steal away from other's story arcs. And I also thought maybe she'd just get fed up of waiting and make smaller, less successful attempts at taking down her stepmother like breaking into the mansion and stuff. 

Maybe the place for these smaller, personal side-stories would be the downtime posts, where everyone leaves the HQ to go and do their own thing. That way it wouldn't require everyone's input but if someone wanted to join in and come to their aid or something, they could make interesting little interludes to set stuff up for later, instead of giant enemy organisations allied against one of our characters suddenly springing up when it's time for their arc.
