One thing I feel I should address about that post: 

Adrian's prior knowledge of Arthur's abilities only goes as far as the fact that he's really fast, fairly durable, and can electrocute via touch. He wouldn't know anything about the ability to guide electrical current, and he never actually saw how he responds to attacks. Arthur attacked first in their last encounter and didn't stop until Adrian was defeated, and the whole encounter lasted only a couple seconds, at most, so there wasn't a lot to analyze in the aftermath.

I'm not asking you to edit, but you've brought up the prior knowledge thing several times now and I feel I need to caution you against bringing up anything else beyond what Adrian actually saw and experienced in their last fight, like you just did in that post.
