A wave of anger surged in Amara. She turned her head and said coldly, “Did you bring Finnian here?”
Dorian was taken aback. He’d only texted Finnian ten minutes ago—how did he show up so fast? Was he already in the neighborhood?
He finally let go of Elysia and, acting like he didn’t have a care in the world, strolled over and opened the door. “Finn, you’re here.”
Finnian walked in, giving Amara a quick once-over. When he saw she was unharmed, his expression eased and he asked, “What’s going on?”
Both Dorian and Elysia were known for their fiery tempers—their fights were never just shouting matches; sometimes things even got physical. Finnian never liked Amara getting involved. He always worried she'd get caught up if things got heated.
Seeing Amara was unscathed, Finnian relaxed, but he still stepped protectively in front of her, making his intentions crystal clear.
Of course, Dorian noticed and scoffed. “Elysia’s pregnant—over two months already. And she never bothered to mention it to me…”
His face darkened again as he spoke.
Then he suddenly caught that Finnian looked utterly unfazed by the news.
It hit him. His eyes went wide. “Wait, Finn, you already knew about this?”
Finnian cast him a glance and replied honestly, “Yeah. I saw the ultrasound report back at your place.”
He didn’t stop there, adding with a jab, “Maybe if you weren’t so oblivious, you would’ve picked up on it too.”
Dorian was left speechless.
