The two go to the Chase Mansion together and fight wolves, look for artifacts, and drink guava juice together. Accolades.
Alex hums Frank Sinatra when he leaves. Alex wears pink and green clothes of all kinds, leading Magnus to be confused before he knew that she was genderfluid. She is the Norse demigod child of Loki and an unknown man. She would be bullied, both verbally and physically, by her classmates and berated by her father while her mortal step-mother did nothing to prevent this domestic abuse.
They wash up and have a meal with the giantess. Alex first meets Halfborn in cheetah form running down the hallways of Valhalla.
The Big Banana takes them to After Magnus turns his ancestral home into a shelter for homeless youths, she helps him manage the place. Alex later decapitated him on the battlefield, saving him from Loki. Alex also wears a lot of outfits. After returning to her human form, she states that she's calmed down already and will not try to "mess anyone up". The next day, they go to meet Loki, and Magnus almost goes into Helheim, but’s Alex’s holds his hand and comforts him, telling him that he can’t go see them, and that she saw her dead grandfathers and friend. After dying and being chosen by her half-sister, Samirah al-Abbas, she has become the newest resident of Hotel Valhalla and a hallmate to Magnus Chase and the people from the Nineteenth Floor. He turns into a wolf and stares down the wolf before it takes a drinking horn by the fire place. He was involved in a pottery studio at one point and went camping with them often, the owners would even let Alex stay at the studio overnight when things were bad at home for the child of Loki. As she rides the elevator with her friends to Thor’s “man-cave”, Alex expresses her initial dislike for Sif, and agrees with Samirah when the latter says that the goddess is both dense and vain.
They eventually defeat the giants – with help arriving in the form of Thor, Blitzen, Hearthstone, Mallory Keen, Halfborn Gunderson, and T.J. – but Loki escapes.
Before Magnus can say anything, Alex kisses him on the lips and tells him that he is still thinking about it, and to go take a shower. After the Greek demigods leave, he and Magnus head to the When they arrive they find the doors blown in and a wolf corpse in the foyer. Blitz hogties Surt with a rope and Alex claims his sword as her own before leaving. She has heterochromia, with one dark brown and one pale amber eye, and her hair is dark at the roots but dyed green. Just then Sam, Blitz, Hearth, T.J., Halfborn and Mallory arrive it see Alex standing over the bested fire lord.
In The Ship of the Dead, the two spend most of their time together and train with Percy and Annabeth. Alex throws a piece of pottery she had made the night before at him as he walks out. He admits that Sam can resist Loki's power by accepting shape shifting and using it as frequently as Alex does. She tells Magnus she was startled by his revelation about their kiss outside Skadi's fortress and needs her space.
He and Sam are picked up by the crew and set sail to pick up Blitz and Hearth. Alex likes to tease people, especially Amir, when he is his male chaperone, and to Magnus. Alex really likes fashion and pottery. Alex has hatred for her father, and says that he doesn’t have feelings and care about her at all.
Alex later tells Magnus that Loki, during the fight, willed her to die. Later, Magnus, Alex, and T.J go to York to fight the giants, and Magnus and Alex talk about Alex’s heritage and Magnus tells her that he admires her, confusing Alex. Back at Hotel Valhalla, Alex offers to help Samirah learn to resist Loki's control, but she refuses, to Alex’s hurt. She didn’t want Magnus healing her after she cut herself because he didn’t want him to see what she had been through. Since she/he prefers feminine clothing and often uses girl pronouns, it is best to assume she/he was born male. Alex has trauma from the abuse she was subjected to from him, and because of that, she had a hard time with other people and will assume that people won’t accept her. NICO DI ANGELO has one job to convince his father to aid the demigods.
By the end of their conversation, Alex has shifted to female, and Magnus knows before he is told. Mr. Fierro expressed his disappointment, saying that she understood the craft of pottery just as much as her grandfather, but Alex corrected him, saying the art, not craft. She wears a pink-and-green argyle sweater-vest over a white tee, skinny lime green jeans, and battered rose high-tops.
