As of A Jailbird, Invalid, Martyr, Cutter, Retard, And Parasitic Twin, Chuckie and his mother have taken to living with the other Gallaghers at their home where they are initially not accepted, since her siblings see them as strangers but let them stay to tend to Frank and give her a chance though warn her of Frank's real personality.

During The Legend of Bonnie & Carl, Chuckie watches a paramedic tend to his grandfather. He is also resistant in leaving until his mothers orders him out, so she could do sexual activities with the paramedic.
After their trailer is destroyed, Chuckie and Samantha come to live with rest of Frank's family at the Gallagher Household. Chuckie soon meets his aunts and uncles who he is happy to see, while they were surprised to have a nephew.
Chuckie starts school with his uncle Carl who defends him from bullies thus, resulting in his admiration for him. Even though Carl initially saw him as a nuisance, he sees that he's just a foolish kid and tells him to stick by him. Chuckie tried to spend time with his "Uncle Carl". While Chuckie sees this as a friendship, Frank suggests that Carl take advantage of Chuckie's lack of intelligence by using him for drug trade. Carl takes Frank's advice and Carl uses Chuckie to smuggle drugs for his mission in Michigan. Chuckie ends up getting caught with the heroin and Sammi makes him tell the cops it was Carl's fault.
Chuckie ends up in Juvie for four months, for possession of illegal drugs. Chuckie's respect for Carl remains, despite him being responsible for him being in Juvie. Chuckie is not very intelligent, and he doesn't really speak much. Chuckie plays a minor role throughout the seasons despite his incidents with Carl. Chuckie and Carl soon come to resent each other because Carl is drafted into a black gang for not giving up his dealer and Chuckie's mother tattoos a swastika on his forehead so the Aryan Brotherhood will claim him.
Chuckie is sentenced to a brief period but his behavior causes his sentence to last longer than Carl, who is released months early for good behavior.
Chuckie returns from Juvie and began living with the Gallaghers, despite them disliking him but came to see he's just naïve and cut him slack.

He is soon found by his grandfather, who feels sympathy for his situation and stays with him through the night. They talk a while with Frank starting to accept him as part of the family, since he previously didn't think much of him. The next day, his grandmother Queenie Slott comes to claim him and he is happy to see her, though put off by watching his grandparents kiss.
Once Fiona buys back the house, Chuckie and Queenie move in with the family. Over time, Frank encouraged him to have a free spirit and be outspoken, despite his misguided views.
Chuckie later moved with his grandmother in a hippie camp along with Frank and his pregnant aunt Debbie.
