Taken from the now deleted Friday Night Funkin' Unofficial Wiki:

Pico has developed an aggressive and homicidal side, rarely showing any fear and ruthlessly fighting anyone standing in his way. He is an exceptional gunman and is usually seen dual-wielding his weaponry with remarkable proficiency. His weapons of choice are automatic weapons such as a MAC-10-like pistol or the M16 rifle. He also has tremendous unarmed combat skills, as seen in Pico 2, the unreleased sequel to Pico's School. He is also shown to be quite paranoid as he isn't too trusting of others and is always armed. Despite this, he has proven himself to be a very trustworthy friend and ally to those he does trust, betraying Daddy Dearest twice to spare and even save/assist Boyfriend when instructed to kill him.

Pico is hired by Daddy Dearest to kill Boyfriend for humiliating him after their sing-off in Week 1. Unbeknownst to him at the time, Pico is sent to kill his ex-boyfriend. Pico is only given a location for his target, and upon finding out that Boyfriend is his target, he decides to spare him and instead challenges him to a rap battle. Despite his previous setback, Pico is later rehired with the simple task of confirming Boyfriend's death after he and Girlfriend are dropped into a dangerous war-zone. However, he finds Boyfriend alive and seeing as Tankmen ordered his men to shoot the two, Pico forfeits his mission and jumps to Boyfriend's rescue by killing the onslaught of Tankmen during the Week 7 track Stress.

Due to his betrayal of Daddy Dearest, Pico is now in big trouble with Girlfriend's parents. The cutscene in Weekend 1 shows Pico running away from and fighting his friends, Nene and Darnell, who are trying to kill him for the betrayal. At the end of Weekend 1 however, Pico and Darnell have reconciled and are friends once again.
