So here's what we know so far

We know that Gisele didn't die in episode 6 when she fell from the plane. But instead was just badly injured. She is very angry with her team for leaving her for dead. She is also very angry with Shaw for killing Han. So she joined forces with Cipher and looking to take out the team. Gisele also killed Brian. Off screen of course. This allows Mia to come back and seek revenge. Anyone know any other confirmed details?
