Michael's eyes opened wide and looked very sharp as he rushed towards them, but Belle entered the car before he could stop her.
He has never felt like an idiot like he was feeling right now, because he knocked on the glass in a hurry, and immediately Gail started the car and was ready to move, he ran towards the front, intending to stop them from leaving, even if it meant risking his life.
He underestimated Gail, because he was ready to knock him down if possible, than staying and letting them talk things out about their relationship.
Gail started the car and moved a bit forward, Michael moved back a bit, yet still refused to move away, looking at Belle who didn't even look up to him.
Michael's eyes and Gail locked. He saw the hatred in them and that further confirmed his assumptions.
This guy wanted to steal his woman away and he wasn't going to let that happen.
