The rule at peregrine nests is that the mother bird is totally in charge. The father bird defers to her.
A corollary is that the mother bird is always present and in charge at hatching time. She calls all the shots, including timing of the first feeding.
The father bird may communicate that he wants something to be different but it's her decision. When Hope tells Terzo, "It's my turn to be on the nest!" he has to leave. When he tells her "An egg is hatching" she takes over. This is the way of the peregrine.
Remember when DC watched (Orion) (?) hatch? He didn't call Beauty and he was kinda surprised!!
Yep, and here is the moment, showing DC's "deer in the headlights" look. True, he didn't call for Beauty, but I believe she was on Mercury and he was looking right at her, as if to say "I didn't break it! Honest!"
