Valentino didn't understand why he said Alice was the problem, he stood there as confused as things were. Valentino wasn't someone who did not have the answer to every question but right now, he still couldn't find a way to explain so, he had to run away before Alice recovered from her shock and started asking him unstoppable questions that had no answer.
Alice was a bit confused and didn't know how to respond to that, she had to rethink to understand what he meant by "You". How come suddenly Alice is now the problem?" How am I the problem? Did I do anything wrong thattoesheconfusese me so much?" Alice was about to tell Valentino how confused she was right now when he walked away and just as he left, Dominic came out of nowhere.
"Hey babe, How is it going?" Dominic knew Valentine could be a douchebag most times, so seeing Alice looking so worn out wasn't an issue.
