Yeah basically what happened is my adc was fighting a little too hardcore, and even when I was trying to protect him and stuff things were going bad. However, he got both of the enemy laners pretty low before he had to flash out. One of them flashed after him, but I exhausted them and dispatched them pretty quickly. Their support was pretty easy after that.
EDIT: The triple was complete and dirty KS though. Was just having fun, since we were trouncing them anyhow.
