Eugene should have expected that answer. Her favoritism of Theseus was noticeable on his end, but Eugene had needed her help after Astrild had left and she'd had dutifully pitched in. Eugene also rather thought Theseus was fond of the fact that Lena spoke to and treated him like someone intelligent, rather than babied him. In time it would likely be the same for the rest of the nephews. There was a big difference between a five year old and newborns, after all. Not to mention, without a mother figure around, there were far were worse options for a strong female role model out there than Lena.

"Entirely fair," at this point Eugene rather thought the two of them would be able to live their unmarried lives in peace, or so he hoped. Lena didn't want to, he thought he was done with romance at this point. Wildly different reasons, but with the same end game. He wasn't struggling to raise his son on his own; Lena was plenty fulfilled with her work. There was no need to dwell on it and whenever his mother brought up the subject, he immediately shot it down in both of their defenses. Being the only boy, he had that luxury and she didn't argue with him, thankfully.

"There's not much to do but hold and feed them as newborns anyway." He would check in on Helga because he had been there and knew just how overwhelming it could be, but aside from that, he knew she had good staff and a present husband, there wasn't much for him to do.
