Ridiculously stupid theory that is extremely unlikely that I had when I was half asleep okay now

Kalista's identity: Senna (unlikely) Yasuo's Master (even more unlikely)

Theory extremely random and unlikely. If someone actually sees logic feel free to spend your time doing nothing particularly productive, or analyzing this. It is really unlikely but it occurred to me and I want to post it before my mind shuts down the idea. :P

And one little useless evidence, if you watch the Kalista spotlight, in teamfights, she has a splash art that has a very specific look. Check it out.
