This was the second night Giana hadn't come home after their argument a few days back and even if they only met at the company the next morning, Dillon could tell that Giana had drunk too much the night before.
Maybe that was also why Giana didn't want to come home, because she knew that Dillon wouldn't take it well when she was drunk.
It was just that, at this point, Dillon was no longer too worried about Giana. Rather he was more worried about the safety of the child in Giana's womb.
How could he not feel anything when his child, whom he had been waiting for its arrival into the world, was being tormented by its own mother who didn't even care about it?
Dillon felt tortured every time he saw Giana like that.
He even tried to give some space to the woman by sleeping in a different room because he thought Giana needed time to cool off, but as it turned out, what she was doing was only putting their child at risk.
