Chase and Leah

The relationship between Chase Davenport and Leah Dooley is the main romantic pairing in the series.

Leah and Chase first meet each other in Crush, Chop, and Burn, where Leah mentions Chase to be a "little cute" in her dialogues. She was the one to show Chase and his siblings a taste of the real world and how to be a normal kid. She was upset when Donald forbade Chase and his siblings from seeing the outside world and was going to send them to Facility X for the rest of their training. Before the kids were sent off, Chase called Leah his and his siblings' first real friend.
