Is something going on? Two very odd AA hands

Was playing William Hill yesterday night. Don't really have any specific reads on 'Babachops', but he seemed to be standard. Nothing to fishy or aggressive, just seemed to be reasonably tight and not that aggressive.

Then this happened... I wasn't involved in the pot, but I was thinking WTF?! WHY?! It came totally out of the blue..Sorry for lack of Hand Converter (i dont think it works with WillHills)

I then started to talk about that hand saying something very fishy was going on. He had never shown aggression before and certainly not like that with top pair...

Then this happened...

I almost folded my AA... but glad I didnt.

He just happened to go all-in on the flop twice when people had ACES? I don't know what I'm suggesting but this was just really ODD!!

He's psychic. But in a bad way.
