Alice Oseman Universe Wiki
SPOILER WARNING: Plot details for Heartstopper (TV series) follow. Caution is advised!

I don't know how I'm supposed to feel when I have a crush on someone. I read all these books where people fall in love, and I still have absolutely no idea. I thought that I might feel that way about you. But then we kissed, and I just knew that I didn't. I think there might be something wrong with me.
―Isaac to James McEwan

Isaac Henderson, portrayed by Tobie Donovan, is a main character in the Netflix adaption of Heartstopper. He is best friends with Charlie Spring, Elle Argent and Tao Xu.

Appearance

To be added.

Personality

Isaac is a kind-hearted, introverted book-worm. In nearly all season one episodes he's shown reading or studying. He is the third member of Charlie and Tao's trio, and is most likely the replacement character for Aled Last. Isaac has little to no lines in the episodes, however when he does give his input, it's always comforting, especially when talking to Charlie Spring.

Sexuality

Isaac initially suspected he had romantic feelings for James McEwan, but after their first kiss realizes that he doesn't. At a queer art gala he comes into contact with the terms aromantic and asexual for the first time. Throughout the second season, his sexual orientation is hinted at but not officially confirmed by his character. At the beginning of the third season, he tells Charlie he is probably asexual and aromantic.

Trivia

  • His MBTI type is INTP/The Logician.
  • He only opens up around his closest friends.
  • Isaac’s sexuality is never stated onscreen until season 3, but as Tao claims he is the “token straight friend” and Charlie says his friends “aren’t gay”. Isaac is confirmed to be aroace by Alice Oseman in a tweet.
  • Isaac is one of two characters from the Netflix adaptation who don’t have a comic counterpart, the other being Imogen Heaney.
    • Though, his character fills the spot in Charlie's friend group usually occupied by Aled Last in the comic.
