Katie and Phineas laid on the couch in the living room, Katie's head resting on Phineas' chest and Phineas arms wrapped around her.

Katie looked up, her green eyes meeting his blue ones, "But…if you want to call the engagement off…go right ahead…I won't blame you an-"
"I'm not going to do that, you big lug," Katie sighed and nuzzled back into his arms, "I just…I know I'm going to be marrying a murderer and-"

I uh…I might have to end this here.
