Marcel and Arianna stared at each other so hard that electricity literally crackled in their gazes. Marcel liked Reina in the beginning until she became interested in Chloe and automatically made herself his enemy. She had many children already, why does she want his sister too? He was not going to share his sister with the woman.
While Marcel was trying to assume his rightful place in Chloe's life and perform his brotherly role, Reina was all motherly instinct and felt Marcel was undeserving of Chloe; the girl would be better off without him. She was a mother and would give the girl a better life and future.
The tension in the room was so thick it was like they were on a battlefield with the lines drawn, except that in this case Marcel was outnumbered, and neither was reinforcement coming. He was all alone and had not made accommodations for this scenario because he never thought Chloe would refuse to come with him.
