Well I liked that they finally made it look like there is an actual "spirit" there having some influence.
Though I still feel that they did a poor job with prior instances. Considering how they made it look like it was all Robbie. Especially since there's an entire prison of bad people, and he only goes after just the one who Robbie had more interest in.
Seems there's still yet more to Mack then we thought.
Though I was kind of hoping that Blaze would come in and Robbie die or something. Still not really caring for Robbie.
The portal Aide made felt kind of like a scientific version of the sling ring from Doctor Strange. But I'm surprised that they not only left it on/active, but also left it in one piece. I mean they've not really had a good history with portals of sorts. lol
An while I knew Aida would be the better solution, I also figured that all that information would have a profound effect on her. Maybe making her independent or seek a independence from her current state of self. Which seems likely with her making a brain of sorts.
Only thing I was really disappointed with in this episode. Was how we see somewhat of the Dark Dimension swallowing things in. Yet no mystical creatures or whatever. Maybe even any weird shadowy figures and eerie sounds just to give you the idea that there's something more there. *sigh*
Overall though. It was a so/so episode.
