Rainbow did not hesitate to fly down full speed to catch the falling Drake. She couldn’t let him die, and she would not let him die.
“Drake! Hold on!” She shouted, as she was getting closer. She caught up with him, and got him with her hooves. Drake looked up at her, in surprise as she took him, and flew back up into the cave. She let him down, now her other friends being present.
“Kid, what were you thinking?!” Rainbow asked. She was happy to see him alive, but he almost got killed. Drake let a few tears fall from his eyes, as he broke down.
“I’m sorry, I had a nightmare where you said that no one would ever love me, and I deserved to die. Then I heard voices telling me to jump off a ledge, so I wouldn’t be a problem anymore and-“ His ranting was cut off when he felt Rainbow wrap her hooves around him. Drake was shocked, but smiled as he hugged back.
“Drake, don’t listen to that other Rainbow Dash, she doesn’t know what she’s talking about.” Rainbow said, pulling away a bit. “You know.... I’ve been growing very attached to you... So much, that I want to adopt you...” Drake gasped, as he let out a smile.
“Really? Can I call you...”
“Yes, you can call me mom.” Rainbow finished for him, as he hugged her tightly.
It was the next day, and the mane six made it back to Equestria. Drake was with them, still a human, and he could walk on clouds somehow. He was at his new cloud home, with Rainbow. He once again felt happy, and his shattered mind was slowly being fixed. Rainbow loved Drake as her son, as the child she saved from the monster that was his father.
