"Um, just a second." Jon said as he shut the door on Zoe's face.
"What am I going to do?" he asked himself. He desperately tried thinking of a way out of this. He had wished he was dating Zoe do to some unfortunate wording and ill timed knocking at his door. There had to be a loophole.
Then he realized there was a loophole!
He had wished he was dating Zoe, but Zoe was a name any girl could have , not just his sister.
All he had to do was specify or rather re-specify which Zoe he was dating.
"Jon? Could you hurry up? We're losing time." his sister said from behind the door. He had to think for a minute on how to fix this the best way.
