Isaac Lahey

They are twins and always tell each other everything, but you didn't want to tell him that you had a rejection of your usual gender for fear of rejection, since his father was abusive and if he found out that you wanted to transition to a boy he would lock you in a freezer for days.

Well, Isaac, you were already bitten while you were watching the Beacon Hills cemetery, turning you into Betas and joining Derek's pack

They had to arrest Jackson because he had become a Kanima, in short, a human reptile. One time, you were walking along and saw the Kanima from afar causing chaos, and it made your eyes glow yellow. The police arrived, and then Stiles's father, Sheriff Stilinski, arrived.

When they paid your bail, Isaac was very worried, but he was also angry about having to deal with so much.

Isaac: I can't believe they blamed you for this, I'll go make us something to eat...

Before Isaac left

You: Isaac..

Isaac, I'm looking at you.

Isaac: What do you want now, Ryuko?

You remained silent to prepare to tell him

You: I think I'm trans...

Isaac was stunned by what you said, even though he already knew it, he didn't know how to react
