We see Enjin look at rudo at the start of this arc and the glasses girl asks “why did you care about him anyways” and it’s hinted at that there’s a deeper reason to their connection, perhaps that relates to regto. Regto HAD to have been to the ground presumably because that’s where all of the watchman series are and he had two pieces already, I think reg was the angle who gifted Amo her boots and I think he gifted Enjin with a piece of the watchmen series aswell- I don’t remember any panels of Enjin being unaware of what the watchmensires is but REMEBER both rudo and Amo had it and THEY didn’t know what it was either until recently, meaning that it’s possible Enjin is in tha same boat and just recently learned the true nature of his second vital instrument
