I wonder if John's power is somehow a psychic ability. I thought that he needed to activate his power while the other person was using theirs in order to copy it. But that doesn't seem to be the case here. Elaine wasn't using her ability in order for John to copy it. Which could mean either 1) John can mimic other peoples ability by psychically read their power, so he needs another person present in order to copy their ability or 2) John just needs to imagine how another persons ability works in order to impersonate it.
The latter case would explain why John could scan and find Sera's wound when Elaine couldnt. Maybe John doesnt copy the ability at all. Maybe he just observes other peoples abilities, imagines how they work, then impersonates/mimics them. If this is the case, John is likely the most powerful person in the comic....
