Curious title, but I've just come across a situation for the first time in three years of playing AHLCG.
Spoiler free.
Patrice is engaged with a Zoog (evade 1) and The Crawling Mist (evade 3) Massive. She uses MoR to evade the Zoog (successfully). MoR allows her to move to a connecting location when successful. The Crawling Mist, which is still engaged, won't follow as it's massive, but does it get an AoO. I think not as the move away isn't an action, which is how I played it. Just wanted it confirming.
Cheers
