I never considered how similar Ed is to his mom in CoS and now I cannot stop thinking about it. That quiet melancholy, the halfhearted smiles, those wistful expressions.
Trisha encouraged Ed and Al to pursue alchemy even though they were like 5 years old, just because it reminded her of their dad. Ed sticks with Alfons because he reminds him of his brother, but it gets to the point where, in a deleted scene, he asks Alfons to call him big brother.
Trisha didn’t give up hope of seeing her husband again, the way Ed doesn’t give up getting back home again, but these aren’t exactly healthy ways of dealing with grief. Mother and son are reluctant to move on and accept their losses. They’re projecting their losses on to other people, and it’s a little messed up.
Trisha’s attention was often on the horizon, on the husband she may never see again. She was thinking about something else, somewhere else, instead of really being there, and it’s a lot like how Ed behaves in CoS, daydreaming about home and the family he may never see again.
I don’t think little Ed and Al understood 100%, but their mom was pretty depressed. Ed and Al performed alchemy so much because it was one of the only things that made Trisha happy, that made her genuinely smile.
In Cos, Ed’s at his happiest when he’s retelling adventures, taking out bad guys, hunting down dragons, and drawing transmutation circles; things that remind him of home and his years traveling with Al. I think he’s actually kinda disappointed when it turns out alter!Bradley’s not a homunculus.
That said, despite some of their unhealthy behaviors Trisha and Ed manage their depression well enough, but the second they’re reminded of their circumstances they grow sad again.
For instance, Trisha was excited to see what her sons had transmuted until she was reminded that Hoho might not come home. Then she has to force a smile and offer false assurances to her son.
Ed was the most excited to test the rocket until he was reminded that he doesn’t have a home. Then he has to go and lay down, lying about his neck hurting and forcing a smile. He doesn’t even want to watch the rocket launch anymore.
Later in the movie, Ed also comforts Al similar to a parent, like Trisha, crouching down and touching Al’s shoulder as he offers Al reassurances and wisdom…Ed’s maturity really showed in this movie, especially compared to Al who’s only 12.
I really can’t stop thinking about Ed becoming like his mom now I’m ruined op thanks
