Whatever the reason, you couldn’t put the egg back in the skillet once it was cooked and Harry was truly and thoroughly cooked.

Byler kiss in Sorcerer episode
“I didn’t love El. I love you.”
That was the bare naked truth of it. As much as Mike didn’t want to like boys, he did. As much as Mike didn’t want to deal with the Upside Down and the demos and Vecna and all of this, he did. Denial only served to strengthen Vecna. He knew that now.
It was the end of the world and Mike was sick and tired of pretending.

Summary
"For the uninformed… Dean and Sam Winchester. Wanted in multiple states. Murders, grave desecration, credit card fraud, grand theft auto - you name it. During their time incarcerated, Hendrickson found this.”
Hotch opened the box and began laying out its contents across the table - passports, credit cards, driver’s licenses. Dozens of them.
"I’m going to assign each of you a selection of identities to look into. I want you to work through each one, track where, when, and how each was used. We'll present our findings on Friday."
OR
The BAU are assigned a deep dive on the Winchester brothers. It may raise more questions than answers.

Summary
Wilson said, “So we’re just two friends who want to have sex with each other, who aren’t going to do anything about it.”
Spoken with the incredulity of a beautiful person with low impulse control. House shrugged.
“We’ve been that for years. Why mess with success?”
Wilson was looking at his mouth. He sounded strained. “I don’t think what we’re doing qualifies as success.”
