Holiday's still learning Shepard, but so far? She really enjoys the other woman's company and conversations. They seem to get along great and would work well together in a work environment or even battlefield. I think after our more recent thread, they'll be a great deal closer and Holiday will certainly trust her more. She's been trying to keep most of the nanite business on the down-low, for the most part, so really trusting someone with all of this at the stage she's at right now is pretty huge for her on any given day.

So, yeah. Basically, I can see a bro-sis relationship blooming out of these two in the near future. It's certainly been long in coming.
