The accusations fly on Wednesday's Fair City as Eoghan finds one of his tyres punctured and thinks Killo and Vinny are responsible.
Seeing the youths, he gets out of his car and says: "You think it's funny, damaging someone's car?"
"What?" asks an incredulous Killo.
"Do you not know how much work I lost out on today because of you?" Eoghan continues.
"We did nothing to you, alright?" says Vinny.
"I could report you!" says Eoghan.
"For what?" Killo replies. "You're the one harassing us!"
With that, Cristiano arrives on the scene and says: "Are they bothering you again? Why can't you just leave him alone?"
Fans can find out what happens next on RTÉ One on Wednesday at 8:00pm.
Fair City airs on RTÉ One on Sundays and Tuesdays to Thursdays.
