A/N: Highly angsty AU. Was meant to be a drabble but overran.
...
Rob is drinking heavily when Cassie appears to him. Her hair is up in a bun, for reasons only his subconscious knows.
"You should probably stop that," she says, nodding at the bottle. "And you didn't have to be such a prick to Sam, by the way."
He keeps his eyes fixed on the glass. "Go away."
"You're still pissed off at me?" she asks. When he doesn't answer, she sighs. "Rob..."
"You promised you wouldn't leave me." He can hear his Dublin accent creeping back in as his voice rises.
"I didn't die on purpose."
"You got in the way of the bullet."
"I saved your life, you ungrateful arsehole."
He finally looks at her. "Fuck you, Cassie."
She stops talking to him after that.
