Soulless Sam in The Third Man:

Cole’s introduction in Black:

Sam’s working breakfast while searching for Dean in Black:
Cole’s last breakfast with his family while searching for Dean in Black:
___________________________________________________________________
Daredevil big brother Dean who got his younger brother hurt in Thinman:
Dean: You know what video would have gone viral, if we still had it? When you were 5 and dressed up as Batman and jumped off the shed cuz you thought you could fly?
Sam: After you jumped fist
Dean: Hey I was 9 and dressed up like Superman. Everybody knows that Batman can’t fly.
Sam: Well, I didn’t know that. I broke my arm.
Dean: I know you did. Man, I drove you to the ER on my handlebars.
.
Daredevil big brother Dave who got younger brother Cole hurt in Black:
Cole: First time I broke my arm, my older brother, Davey, had me riding on the handles of his three speed, decided to pop us a wheelie, look real fancy for all of the pretties outside the DQ. Well, we were looking mighty good for a little bit, and then “whoop,” ass over teakettle, boy. Hurt like a son of a bitch.

What conclusions to draw from this parallel?
I’m betting:
a. Davey, Cole’s older brother is being brought into parallel with Dean and so I’m betting that Davey, too, got turned into something evil.
b. A werewolf, if Cole’s “moons and moons ago” means anything.
c. Dean killed Cole’s older brother.
d. Is Sam going to kill Cole, then?
