I wanted to reply to a review but you were on Guest so this is the only way.

"I don't want to seem like a bitch or anything by saying this but I think if you rewarch it you will find Tyler three the bottle at the wall not Caroline. I'm pretty sure Tyler being the athlete he is would of hit her if that's what he was aiming for."

I know he threw the bottle at the wall. That's why I have the bottle hitting the wall and shards of glass being what cut Caroline. Tyler didn't hit Caroline with the bottle because he was not aiming at her.

This one-shot was a prompt from Tumblr-"Tyler hits Caroline with the bottle and Klaus sees". I wrote it this way instead because I do not believe Tyler would ever intentionally hit Caroline with a bottle, and he's not a bad enough aim to accidently hit her with it.
