Senel is a pretty good guess, actually, but not quite it.
1. Relations with my family? Awkward.
2. My upper-body strength is quite good.
3. So, according to this piece of evidence, I participated in that mission? ...no, that can't be right, my memory is fine and I'm sure I wasn't there. Must be mistaken, or from an alternate universe, or something.
4. Both my left and my right are exceptionally powerful - as my disliked relative can attest.
