  Langstrom: Did I hurt anyone?

  Nightwing: Calm down, you can do it. (obviously feeling rather awkward) I... believe in you.
  Flash: (suddenly gives Nightwing a hug) Thanks man, I needed that.
  Nightwing: (now feeling really awkward) Oh come on, alright, just-- please just get off me.

  Red Robin: Dr. Langstrom, please! Your body has changed but not your mind. Concentrate!
