She has also been involved in a relationship with fellow youth offender Curtis Donovan (Nathan Stewart-Jarrett) and later Simon Bellamy (Iwan Rheon).

[1] Thomas trained at the Bristol Old Vic Theatre School and won the part the day after leaving.

[4] Thomas said she and other cast members were undecided on returning for a third series, adding that it is "quite difficult so early on to make a decision for next year and to know what you’re doing.

Thomas later confirmed her exit, saying she would not be returning for a fourth series although she has had an "amazing time" at the show.

This party girl’s biggest concern is that she retains the title of Miss Shagable for another year running.

Our superficial and sassy stunner (and don't forget potty-mouthed) is now stuck with the worst come down of all: a day job that might as well be shovelling shit for all she cares.

Not only is Alisha cut off from her mates, forced to associate with losers all day and has a curfew; she’s also got a power that could seriously damage her social life.

Thomas commented that "when she [Alisha] breaks the law, she ends up doing community service with a bunch of others who are totally different to her and slowly she loses the front and we start to see her vulnerable side".

[12] Tim Dowling of The Guardian described her as the "slutty one" of the group of "foul-mouthed young criminals".

[14] While at college, Alisha took Rudy Wade's (Joseph Gilgun) virginity, and ignored him the following day.

[16] While on community service Alisha is caught in a storm which gives her the power of causing those she touches to go into a sexual frenzy.

[17] Alisha continues to flirt with Curtis and when he rejects her advances she touches him, causing him to go into a sexual frenzy.

[21] Lucy (Evelyn Hoskins), who has the power to shape-shift, takes on Alisha's appearance and gives Simon Bellamy (Iwan Rheon) oral sex.

She walks in on him cradling a dying Charlie (Nathalie Emmanuel) who has been stabbed by Tanya (Katie Moore).

Rudy kicks Tanya who falls and cracks her head open on the floor, killing her.

[28] In an alternate timeline where the Nazis won World War II Alisha is dating Shaun (Craig Parkinson).

[29] The spirits of Sally (Alex Reid), Tony (Danny Sapani) and Rachel are brought back.

Simon decides he must now become Superhoodie, so he travels back to the past where the previous events play out again.

[30] Thomas received overwhelming positive reception for her portrayal, many noting her ability to bring sympathy, depth and likability to the character.

Thomas was nominated for Outstanding Actress in the fiction category at the Monte-Carlo Television Festival in 2011 for her portrayal of Alisha.

[31] The Guardian felt Alisha gave them "something to cheer about" as she is a female character in a British science fiction serial who doesn't "exist just to be rescued".

They added that Alisha's "notorious "sex power", meanwhile, proved problematic for feminists everywhere – and deeply uncomfortable to watch.

In choosing her new power (which allows her to see what other people are doing) and a relationship with Simon, she's also chosen to embrace both the superhero life and her own vulnerability, despite knowing that disaster likely awaits in both.

[35] Writing for The Guardian Tim Dowling said "Alisha’s infatuation with him [Simon] gives rise to a love scene that I can only describe as extremely grown-up".

They added that they "loved" Alisha's speech to Tony telling him the group had tried their best because it made "what was to come all the more shocking".
