Tear Jerker / Jane and the Dragon

• The episode Dragon Egg. Dragon, having spent the last 300 years believing himself to be the last of his kind and searching for some shred of hope, is overjoyed when he attains a dragon's egg from the merchant, taking great effort to take care of the egg and provide it a nice home when it hatches. His obvious pain and heartbreak when he finds out that the "egg" is just a rock from the quarry will get you.
• Dragon tries to get Jane to remember who he is and get over her fear of him after she gets amnesia, and almost doesn't succeed. The look on his face after she tells him she hates him is heartbreaking.
• Smithy's speech in "A Pig of a Problem"—you can hear his voice cracking.
  Pig is going. Forever. Or she will be, and I need her. Need her in my forge—work in company, I guess. She has never let me down, not once. Never too tired, you know? Always there and never asks me for anything. And now how can I help her—how can I? Right when she needs me!
