Spoilers for the finale of RFTH Plagueground!!
Im just thinking about how Edgar will have to take care of this new egg but how Midge definitely didn't think about how baby birds are fucking fragile and Edgar is just a young teen who's still doing classes.
Imagine Edgar is sat at his desk in his dorm room at night, Monty is asleep and Edgar is struggling to do his homework—continuously getting distracted by the egg sat on Poe's old birds nest being bathed in a warm light. Edgar whispers to it, wondering what it'll be like. Is it going to be as confident and stubborn (/pos) as Poe? Or will its personality completely contradict him? Will this bird even be a crow? Edgar would probably start entirely new research, going to the libraries (if St Churnley's has any or during the summer holidays) to research birds to help identify it. He would be completely invested in this new bird as a part of his healing from losing Poe, but also as a distraction.
When the bird is born and Edgar is the most caring person ever. The bird immediately imprints on Edgar, seeing him as his mother. Since Edgar is studying and is busy with his classes, the bird will probably have to go to Nurse Lenny to be taken care of during the day so during lunch, Edgar will visit and even make a friendship between him and Nurse Lenny. During these visits, Edgar tries to be as present as he can, Nurse Lenny will teach him how to feed the bird and teach him how to tend to its wounds in any future battles (which Edgar is extremely appreciative of because now more than ever, he wants to be able to save this bird like how he could've saved Poe). As a bonus, he takes up extra lessons with Sarge and goes to the gym (as Poe wanted) to make sure he is strong and prepared for whatever future battles may occur so he is ready to protect this bird and it won't ever have to think of making the same decision Poe had to make.
When the bird grows up, (assuming its a crow and is the exact same size as Poe) Edgar has this dramatic moment where instead of passing on Poe's old armour to the new bird, Edgar creates an entirely new one. He's been perfecting this, even taking up classes with Mr Hebden to help teach him the aerodynamics and physics of the armour he wants to create, in the process, making many different types with all different looks and materials, until he makes one that is just perfect. Edgar wants to make sure this armour is perfect so that it can withstand everything that Poe had gone up against during the initial fight with that monster so that it can protect this bird when he cannot.
