Good point about traits vs. DNA. As for knowing Walter had a son, he got a hold of Walters sweater somehow. I'm guessing this guy who's apparently been alive way too long did a little research, and I'm sure it couldn't be that hard to find that Peter existed. And depending on if he did said research, I suppose he…

Nobody noticed?
Peter wasn't affected by the version created to target Walter's DNA. This would make sense, it being the alternate-Peter and all. Or was this virus made so specifically to ONLY affect Walter?

I'm excited..
for this. Especially the input from Mr. Moodell.

Let's hope…
that Conan's last episode is amoosing.
