What would you have done in Michelle's shoes ?

I'd have said "Fine, hope you have a great time/life but if (not when) it all falls apart i'm here for you (but not her).

I think the situation between them has got so entrenched that the best thing she could do is just let him get on with it and go, and call toxics bluff, but make sure he knows she's there for him if he needs her.

It's now a got to let him fall situation, but be there to pick him up when it does.

It was Ken's reaction that amused me:

"Glasgow," said Ken, with a look of disdain - completely forgetting he'd sent his own children there after their mother died...

I would do that too.

They are worried about Ryan going off so far away with Tracy because Tracy is dangerous (thank god they FINALLY said it in tonight's episode, though they still skirted around the issue that she's an actual murderer).

But the more they try and warn him the closer they get and he fights back. Got to let him find out for himself now.

I completey agree and in almost any other circumstances I'd do what you suggest. But if my son was running off with a known murderer I don't think I'd have the strength to say "fine, off you go then."

Since it's Tracy I'd have preferred Australia.
