"You're the Inspiration." The agents help a little girl to cope with her father's death, supporting her while she is trying to help her mother and honor her father's memory. Their help actually manages to bring the father's spirit back to his family just in time for Christmas, allowing him to fulfill his last promise to his daughter.
In the finale (Jumpin' Jack Flash):
Lucy gets to return the favor of the EBA letting her see her dad one more time by starting the chant that saves them. It's also very awesome.
As the Agents shout "ARE YOU READY?", but right before the usual "3, 2, 1, GO!" countdown, you see everyone cheering the Agents with a "YEAH!".
