Wait!! So that's why sometimes in previous seasons Leez wasn't herself? And she did things...

Those were "black out" scenes, we didn't see what lead up to the scenes that happened just the before she lost herself to the "future" her and after the release. So we were only told she was acting strange, but never saw or learned what happened to lead up to the issue just the looks they had afterwards.

After that bit we learned what happened lol.

Oh pfft I read that wrong I thought you asked why not that you were stating xD
