Is Cobra coming back for a second time?

Recently, Forrest returned, probably specifically for this occasion, although after the last incident when the Great One was saved by Cobra, he promised not to return. Now, let's say that Alexa should be banned for cheating, and Forrest will leave us again. I've played with Alexa several times, and after the games, I looked at the saves (and especially the replays). I had a strong feeling that he was peeking... but it's hard to prove. I just decided for myself that he's cheating and it's better not to play with him.
