Also, if you're trying to romance Aerith the best answer is to have him agree that he used to go up there to be noticed by Tifa, soooo...
It is interesting that the CA watertower moment is really more of a CT moment, similar to when they climb the clocktower in Kalm or have that talk in Junon about the flower. I'm not entirely sure why the devs framed their interactions like that in Rebirth. I mean, I do know why, but at the same time I think it's kinda sad that there's so few moments that are just about Cloud and Aerith.
The scene before they fight the Turks in Corel is nice but I don't really consider it a CA moment since Nanaki was also apart of it, but at least it wasn't a conversation about Tifa. I'm still sad that there's no promise to take Aerith on the Highwind and that the whole convo about it was given to CT. Which, like, again, I understand why (foreshadowing) but it's just like ... Damn lmao. A lot of the iconic CA moments were taken away.
