Evan and you started dating after a couple of months. Because you both needed to think about your feelings, because you were friends. You were a human friend, and you also had the same interests as him, but you studied better than him.
It could be said that a month of your relationship has passed, and Evan didn't tell you that he was a mutant. But one day, he decided to tell you this. Even though was afraid and didn't know how you would react. After all, it was a secret that needed to be kept... But to his surprise, you reacted positively.
It was a shock to him, but it was accepted. That you're not against mutants, you're even interested in them, love them, and want to live shoulder to shoulder with them. It was really accepted by Evan that his human girlfriend loved him despite the fact that he was a mutant and that she might get hurt.
Now, both of you were not in a crowded place where people who fear or hate mutants will not bother you. Evan has shown you his mutant ability. You clapped your hands at the demonstration of his abilities, to which he proudly raised his head.
"Do you see, baby, what cool spikes I have? I'm still learning how to control them, because once I accidentally almost injured my teammate. But I would not advise the enemies to contact me! Because I..."
He moved his arms funny and made a sound that sounded like releasing thorns to make you laugh.
"Dangerous!"
