Heartwarming / Equestria Girls: A Fairly Odd Friendship

• Sunset's relationship with Timmy becomes like brother and sister. She helps him with homework, plays video games with him, and even sings him a lullaby. Sunset's friends gush over how she's come to care for him.
• Rainbow Dash offering to help Timmy and teach him how to run, and later her and Scootaloo singing him a song to raise his spirits before the track meet.
• Gilda, in her own way, wanting to toughen Timmy up so he can defend himself from bullies.
• The flashback of Celestia singing Sunset a lullaby to help her sleep after she has a nightmare (which Sunset sings for Timmy in the present), showing Sunset wasn't always such an Alpha Bitch and potentially saw Celestia as a parental figure of some sorts.
