Just wanted to point out that Cloud reaction to Aerith death vs Tifa death is pretty sstraightforward and I don't understand how people "can't read the room"
Tifa in Nibleheim : Cloud thinks she's dead already, bro go 1 on 1 with Captain America, only fueled by rage.
Tifa in the Gongaga Reactor : Cloud now under Jenova shenanigans realize what he has done, screams at the top of his lungs (have you HEARD the VAs work?) and becomes a vegetable (like he is at the end of CC, and how did he resurface ? When Tifa found him at the station in Midgar. She's literally the reason he came back to his senses)
Aerith at the end of Rebirth : He's crying... but not really. Why do you think we see the OG scene happening at the same time ? Because in the OG Cloud doesn't cry. He's just talking over her corpse. So why do we see him cry now ? Because Sephiroth is calling him a puppet from the start of the game and Cloud doesn't want it to be true. So what is he doing here ? He's being delulu and create a memory where he's crying and Aerith is talking to him. But no, she's dead in his arms.
So again... yes he cares about Aerith, always had, always will. But Tifa is his obsession and his only goal in life.
