I've been wondering about that.
It's probably one of the reasons Jack was so surprised to see him in Russia.
Is it possible to deal your way out of treason? I have no idea, but if anyone could weasel their way out of it Maybourne could.
I'd just chalk it up to another "whoops, we didn't think that through" from the writers. I'm glad he's back, though.
Or....maybe he ran off before the, ahem, stuff hit the fan. I'm sure he didn't plan on getting caught assisting the Russians
Don't mind me, apparently I'm just posting to post. If I had a point it was lost long ago:dead:
