Kate Kane will be going on the mission because she hasn't been on any, needs to know how things/people work on these, and because she is here to help this war. I don't think she'll make an appearance as Batwoman this time.

When she gets back and because the plot's going to last two weeks, she'll be affected by the timeline disruption later on. I don't know what point I'll choose yet, but we can try to plot something anyway! I'm thinking either trainwreck 12 year old or trainwreck 20 something year old who just got kicked from West Point. Decisions.
