Going back to a recurring theme, if Aerith is the past, then Tifa is the present. Just something that occurred to me when think about Tifa. If you look at her life since she was about 16, she never gets the chance to just be.

Tifa.
Present: being, existing, or occurring at this time or now; current.
"Sometimes… I wished time could just stop."
"What do you mean?"
"I… just wanted to stay in the moment…"
"… the moment?"
"… I never really got the chance to… just sit… and be."
"… I don't think I understand."
"… sometimes I just wanted to stop… I just wanted to think about here and now… and nothing else…"
"… Tifa…?"
"… well now I've got that wish…"
"… I…"
"… I can't go back Cloud, you know that…"
"… Teef…"
"… and there's no going forward… not for me…"
"…"
"… there's just this… just the present…"
