[quote name='Ser Scot A Ellison' post='1294897' date='Mar 31 2008, 12.36']I can't believe Slynt would have known of Tywin's murder without Jon knowing first. If Slynt did somehow get that big news before Jon then Jon was taking a much bigger risk than we thought in seizeing and executing Slynt.[/quote]
I don't think so. I'm pretty sure Jon realizes that Tywin has much more important things to take care of then worry about Janos Slynt being executed on the well. Besides, Tywin doesn't have any power on the wall, except Slynt, to get back at Jon. If he did do something, I think it would be years before, (unless he plans to send some assassins), and I think Jon realises that his struggle with the others will peak before then.
Speaking of assassins, were they sent? Or did that plan get interrupted by what happened to Cersei? I know she wanted to send one of the Kettlebacks to kill Jon.
