It can only end in one of two ways...Stallone fights and loses but fights valiantly...or he wins. I think Stallone leaked a shot of the script that showed the outcome...unless his intent was deliberately to mislead by posting the photo. This sounds like he starts off training the guy...then he ends up fighting him because he turns into a cocky thug...as in Rocky V? I dunno. I'm sure Stallone will come up with yet another angle that is semi-original as to how Rocky ends up back in the ring. The last one was because of a SportsCenter computer program saying Stallone would be the current heavy weight champ I think. lol
Hopefully Creed is more about the grandson than Rocky. Cause if he's a supporting character , in the Micky role basically, I'd be fine watching it. And maybe he can do for Rambo what he did for Rocky in the final installment. From rumors I heard awhile back that may be the angle he's going for.
He isn't fighting in Creed. At least nothing I've heard or read indicates that is part of the script.
