Gouken's return to Ken and Ryu. In the original Street Fighter IV, Gouken risks his life after having just awoken from a ten year coma in a battle with Akuma, for the chance to seal away the Killing Intent within an unconscious Ryu. Then he disappears before Ryu awakens. Later, He appears on a cliff, looking down at Ken and Ryu, resolving to test their strength and see how they have grown as men. When he catches up with them, they beg him to stay with them for awhile, only for him to tell them that they have grown and no longer need a master to take care of them.
Guy's continued concern for his best friend Cody, even after all that's happened between them and how Cody has changed.
