Nico
While Nico was ever the doting uncle to Cassie's kids, he still wasn't sure how he felt about Seth being the father of Alex's child. Or that Alex was pregnant at all. Because it meant he thought too much about how things happened and if the stork brought babies, it would be a much simpler and easier process to digest. Instead.. whatever kid Alex had would be part Thorne and part entitled-socially-awkward-weirdo brat and he wasn't sure what to do with that. He also hoped that none of his siblings started pushing him to have kids, because he was not ready for the path of fatherdom anytime soon.
"Sisters do that, apparently," he replied with a slight drawl. "Go through things." To some extent, all of his siblings had dealt with sadness or pain. Cassie's had felt like a betrayal. Ren's had turned into something beautiful, it seemed. He gave her a look, though. "I'll try. But no promises. He's just so..." He made a face, scrunching his nose. "Boring."
As she leaned into him, he relaxed a little, closing his eyes as he appreciated the comfort of being home. While Alex had never exactly been the 'mom' figure in his life, she was a close second to Cassie. "Well, when work calls, I go. It's been the same old thing as always. Nothing crazy."
