Heartwarming / Rose of Pollux

• Just seeing the Eleventh Doctor interacting with babies and small children is always heartwarming. When the baby he's interacting with is a very young Jamie in Great Things? Priceless.
• The note Jamie writes to the Doctor during ''A Lifetime Away'', which takes place on the first Christmas Jamie has after losing his family and starting traveling with the Doctor:
  Thank you fer bringing me too the citi
  I din think I wood be happy on krismis but I am
  Thank you for making me happy.
  Happy krismis
  —Jamie
• This exchange from Metamorphosis:
  Jamie: I knew if I was the Piper, I’d be something, and he knew it, too. …Och, but it doesnae matter now, does it? I’m nothing again.
  The Doctor: “Jamie, you are everything to me.”
• From Part Five of You and I, when the Doctor realizes that Jamie is still alive, his reaction will evoke an 'aww' from anyone reading.
