Heartwarming / Next Avengers: Heroes of Tomorrow

• Just before the big showdown with Ultron, Toruun is sitting alone (minus her sword). She starts trying to talk to her father (Thor) again. Telling him how scared and useless she's feeling. After she humbly asks for his help, her sword magically comes back to her, and she smiles.
  Torunn: Father, please help us. I'm scared for my brothers, for Tony, for Hawkeye. They need me. If you ever cared for me, please help me now. Help me save my family. I'm begging you. Lend me your strength. (Torunn's sword flies to her location, landing near her) Thank you, Father. Thank you.
• When Torunn and her dad share a hug near the end of the movie.
  Torunn: Home... Oh, Father. I can't believe I'm saying this, but my home is with my family on Earth.
  Thor: I know, my daughter. But know that the doors to Asgard are always open to you, and when the time comes, you will be welcomed.
• Just the idea of Tony Stark, Mr. Irresponsible himself, doing his best to raise four super-powered kids as a single father as atonement for having built Ultron in the first place.
• Betty getting to hug Bruce after being apart for decades.
