"I'm really sorry, for messing up your plans, baby. I didn't know that i would be taken that night…" Raquel apologized to Igor, based on his plans to eliminate Vladmir on the day Giovanni was initiated into their family's business. She's the reason why Vladmir was still walking on his two feets, and she knew how hard Igor had planned, and waited for such an opportunity to come by.
He hasn't been able to leave her sight since they came back, and neither did he look like he was worried about Vladmir, since he's sticking around her like she's going to disappear from his eyes any minute, hence, the big bad wolf was in love.
It still wasn't explainable how the both of them got deep into what started as nothing but a casual fling. Raquel could still remember how she met him, she was meant to be sold at a whorehouse by a rival gang that killed her family, and Igor bought her.
