Re: Gideon
I think it's possible Gideon could find out from the reports from Nadia, since Jax is one of her main targets...and he hasn't made it much of a secret that he doesn't approve of Jesse's presence in town...for REASONS. Nadia may not be able to consciously remember things about the supernatural, but her subconscious still registers and records it. Plus, there are other "spies" around WC who report to the military. I think since Gideon's been staying on base in July, he's had some time to review pertinent information. He also would have followed up with research about Elise, just to double-check all the things.
But yes, we need some real Jesse and Gideon interaction in August!
