Vid is good, but Big Daniel ain't a child of Shingen, it's been HEAVILY implied that ALL of Shingen's children aside from Gun got executed by Shintaro---most likely also Shingen's wives---and it's been implied since Gun's backstory. Plus, if Big Daniel was truly Gun's half-brother, then he should've been the same age as Gun since all of Shingen's children were born on the same day. Also, we need part 2, now.
