Day 3 Edit
Sergio was playing with one of Hector's guns when Hector found it missing. On alert for an intruder, Hector was initially angry with Sergio for taking what wasn't his, but then relaxed and gave the boy a shooting lesson, telling him, "this is what power feels like."
Later, when Claudia told Sergio to get packed up so they could leave quickly, Sergio asked Hector to convince her to stay, not realizing that he was putting them all in danger by telling Hector about the escape plan.
