Blaise smiled in encouragement as she began to talk, her first admission catching him by surprise and making his heart pound. She loved him? He thought he felt his stomach twist in knots but the longer he thought about it, the more he realised it made perfect sense. They had been friends for a longtime and lovers almost as long as they had both been old enough to know what it meant. He knew without a doubt that he loved her in some measure but had never stopped to consider how much.
He didn't make a comment, just absorbed the first three things in silence. He would react at some point but he wanted to hear all four things before he reacted. He was very pleased she was no longer married, it did make the first admission easier to reciprocate if she was truly single.
Her fourth admission made his heart sink and he inhaled sharply as anger rose. His brain didn't hear beyond the I'm pregnant and he immediately wanted to growl in jealousy at her now ex husband's spawn in her stomach. He took the parchment she offered him and stared at the page blankly.
Frowning as her words pierced the haze collecting in his brain, he looked at her, furrowing his brow in confusion. "You weren't sleeping with Montague and as far as I know you didn't have any lovers.." He leaned forward. "Are you saying it's mine?" He searched her face, confusion clouding his dark eyes. It made sense although he knew for a fact they had used potions. "But we were careful." He looked at her stomach for a long moment before meeting her gaze.
