The weird thing is that I readjusted the trailer the cast or two casts before the bite, and I would think that in my infinite awareness on the water
that I would have noticed the bent hook when I readjusted the trailer. The cast or two after adjusting the trailer were pitches to the outside of pilings; which didn't really hit anything but the bottom. So the only thing I can deduce is that it got bent on the bite. Also, the bite/hookset never pulled the trailer out of place, it just looked out of place because of the hook being bent.
I'm not denying I don't whack my fair share of docks throughout the day though, so that's definitely a possibility, I just think I would have noticed it being that way while I readjusted the trailer and made those two pitches. I didn't even think about that so thanks.
