Mickey slowly matured as the show progressed, becoming less violent and aggressive and more kind to people, something which results in further mockery by his biological family.
The early episodes of the sixth series show Mickey attending college to study film.
When he reveals to his parents that he wants to pursue further education, Paddy and Mimi (Tina Malone) ridicule him.
Later on in the series, Mimi accepts the fact that Mickey is going to college and supports her son in his educational endeavours.
Mickey decides that his true talents are in erotic writing and gives up his place in the class for his mother, Mimi, who loves films and has always wanted to go to college.
He informs Maxine that all he wants is that when she finally realises she cannot be happy with a gay man, that she lets Ian down gently.
[2] Mickey leaves Chatsworth during ninth series after helping a young woman, Liz, give birth to a baby girl.
[3] Mikhailo Aleksandr Milkovich, nicknamed Mickey, on the American remake Shameless is portrayed by Noel Fisher.
"[4] The only reference in the show is in Season 2, where Mickey says that he's not going back to school because he'd still be a freshman due to not passing classes the previous year.
In Season 1, Mickey is presented as the neighbourhood thug, violent and homophobic, but as the series goes on, it is revealed to the audience that he's secretly gay.
[7] Mickey and Ian launch a criminal enterprise: robbing closeted wealthy gay men and threaten to out them if they report the crime.
Mickey and Terry get into a fist fight, and Ian unsuccessfully attempts to intervene until the police are called.
Terry is sent back to jail for violating probation, while Mickey is released by a sympathetic gay officer.
[9] Following his manic behaviour throughout the season, Mickey finds Ian laid up in bed in a deep depression, so he calls the Gallaghers who worry that he has inherited their mother, Monica's bipolar disorder.
[10] Later that night, Mickey watches Ian being arrested by the military police, which was called by Sammi, Frank's oldest daughter.
This paranoia causes Mickey to initially mistake his parole officer and some of the new occupants of the Gallagher house for the gang.
Ian later admits that he has insecurities about the effects his mental health can have on their relationship and how he believes Mickey deserves better instead of settling down with him.
Ian's friends and family come together to plan a new ceremony on short notice at a polka hall owned by an old flame of Frank's.
In Season 11, Mickey and Ian adjust to married life whilst dodging the usual "Gallavich" antics living with both Gallaghers and Sandy Milkovich under the same roof.
He has trouble finding a regular, non-criminal job after Ian urges him to get one to take care of half of the couple's bills, eventually cursing out the manager of the warehouse Ian works at and stealing recently-expired boxes of food to sell at a reduced rate.
He begins making money by running an armed transport service used by several legal cannabis dealers throughout the city of Chicago.
Prior to his death, Mickey frequently chided his siblings and cousins for not taking care of him, as he was incapacitated by an injury and could not feed or clothe himself.
