Is Martin really the father of Finn?

it's assumed that Martin is finn's dad. although no hard evidence other than the fact that they're both human and Billy stated he was.

we may not be 100% sure on it but it's pretty much được trao that he is.

Yeah mostly what TFF said. I don't remember if Bill đã đưa ý kiến Finn your dad is at the Citadel hoặc if Billy specifically stated that Martin was at the Citadel. Because if he didn't specify then Finn just ran up to the first white guy he saw and called him dad. That would explain why Martin couldn't explain why he left Finn.

Well, it might have been him hoặc not. Even if it was đã đưa ý kiến that he was located at the place where he was doesn't necessarily mean that it's actually him. There might have been another human there. If not, then one of them might have been normally a human but just have been made into another form. Whatever the answer is they still haven't made an arc that answered it completely correct . _ .
