Heartwarming / Ben 10/Generator Rex: Heroes United

  • Long before Rex and Ben become friends (much less start getting along) they both call "Time-out! Innocents!" when they notice that some civilians are in danger. Since they both made the call at the same time, they pause and give each other a surprised look, then quickly go about saving lives.
  • Ben revealing he could have gotten out any time he wanted, he just wanted to see if there was anything he could do to help the comatose Six. Pretty nice, considering he only just met these people in a Let's You and Him Fight way.
  • Rex hugging Six after finding out he's out of his coma. And Six's positive reaction towards the gesture, rather than saying something like, "Stop hugging me, Rex."
