Gaz had anxiety. Anxiety about losing you, like he had lost other people. You made the mistake of promising him that you'd stay. You wish you could take it back now.

Now that you wanted to leave.

He was too focused on his own issues to care about you. Well, he did, but he didn't show it like he should've. He never listened like you did for him.

He stood in silence, his eyes processing the information as you explained.

"Are you serious?" He asks. He wanted you to say you to say it was a joke.
