"...what's going on," is the first thing out of his mouth, when he sees the looks on his parents' faces. Maybe he should already know, but — he doesn't.
Christine continues to ask questions with the theme of 'have you considered that being gay is maybe actually bad?'
He continues to answer them on the theme of "Being gay is awesome, actually" until his session is over.
Christine begins by talking with him for a few minutes about sports, before saying "Marlo, do you mind if we talk for a bit about your homosexuality?"
"On a scale from 1 to 10, where 10 is definitely ready to change your homosexuality and 1 is definitely not ready to change your homosexuality, how ready are you to change?"
He almost says ten before he pauses, thinks about it, and says "Nine to nine and a half."
Because he's lying for Sasha and Asher. "Because at this point I should know not to give answers that certain."
"It sounds like you are very motivated to change. On a scale of one to ten, can you tell me how confident you feel in your ability to change?"
"...I was trying to be normal for most of my life and apparently it didn't work at all."
"People become homosexual because of a trauma, called a root. Some roots are very serious traumas, like abuse or neglect from a parent. But some can seem very small, like feeling like you didn't really have any friends at a close age. You can't stop being homosexual by trying to be normal. You have to work through your root, which caused you to inappropriately sexualize your desire for closeness with other men."
"...the earliest I can tell was my best friend in elementary school —" and he describes Leo, who'd been the smallest kid on the playground and the smartest kid in their class and who Marlo had protected from bullies, and how Marlo had thought he just admired and wanted to be friends with him but in retrospect it was almost certainly a crush.
"He was also my best friend. It was — good to be someone who could protect the people I was close to."
