That's the first thing I thought. He's been known to power various attachments and even independent parts of himself. They should have had at least a throwaway line how his energy isn't compatible with the remotes. You know, like holodeck energy. We all believed that, right?
This was moderately funny for me. About par for this series IMO. Also, I've noticed that the Cat was wearing a plaid outfit he's ACTUALLY WORN BEFORE. I don't know how many times this has actually happened, but it's pretty few! The cast commented early on that Danny John Jules hasn't changed a bit physically, where everyone else has had to have larger wardrobe created. If this was the actual costume he wore previously, we shouldn't be surprised!
