Oh, if Sparky actually gets kidnapped I can see Hitch going full-on Liam Neeson in Taken.
" I don't know who you are. I don't know what you want. If you are looking for ransom, I can tell you I don't have bits. But what I do have are a very particular set of skills, skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my baby go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I WILL BEFRIEND you."
I'm not sure if Sparky will ACTUALLY get stolen, or if his kidnapping will just be a distraction for Opaline to go after the Unity Crystals again. We probably still need to pay off that crystal-cracking moment from the Special, after all. Maybe she'll actually get ALL the things she's been after in MYM, the Crystals, the Lantern, and the Baby.
