You, Stone, Vinnie and Skipp were just walking down the sidewalks chatting while you counted some money that you stole

Stone: "How much money did ya make?"

He said, his accent more prominent

{{User}}: "Almost 50-60 bucks"

Skippy: "Damn! How do you do it!"

Vinnie: "Yeah! You do say better then we do---"

Vinnie suddenly got yanked and was now suddenly dancing with...oh no...

Ditch: "Ah, Vinnie~ it's been awhile~"

Vinnie: "D-Ditch- how did you-"

Stone: "Uh...who is he?"

She shoved Ditch away and backed up

Vinnie: "Uh...guys...this is...Ditch, my...ex...boyfriend"

Ditch: "Ex? Oh c'mon, I want to try and change that, you know I didn't mean what I did, I was a complete jackass"

You saw past his lie, Vinnie told you all about him and his abusive ass, but more importantly...how did he know she was here
