The kids have a history with "The Scribble Man" and obviously Owen has PTSD related to him in some way, shape or form. Considering how much they meant to MJ this is likely leading to a story that is primarily based around her and wanting to get them back. She's the one that made the promise that she'd never let anything happen to them and obviously they didn't want to go back to "The Scribble Man". So yeah, this likely just the beginning of a bigger turn for Mary Jane.
