Why did Allen feel like something was about to happen? Why did Allen know exactly who this was as soo as he was pounced on?

This was perfectly normal. He didn't have enough time to react and unfortunately for his luck ended up on the ground. A part of him wondering if his bad luck was getting a bit out of control today or something.

It was always possible since he never really got a good handle on it.

"Hey Esteban. Are you playing a game that I wasn't told about?" he said with a bit of a laugh behind it. He wasn't mad at least he was pretty much use to it.
