It’s Soldier Boy, who has secretly been kept alive all this time in cryogenic stasis.

Ackles also confirms hisCast Away-esque beard was legit.

“I didn’t know that I could grow a beard,” the actor remarks.

“It became its own thing.

My wife was done with it.

She was like ‘Enough with the beard.

Can we get rid of that?'”

Soldier Boy’s debut onThe Boyswas a lot more explosive than just beard and butt.

They quickly realize that her wounds aren’t healing by themselves, as they normally would.

Eric Kripke, the series executive producer, explains this change to Soldier Boy.
