HI there, long time fan, first time commenter.
I have no idea what 'that's it' is supposed to mean in this context? It isn't a phrase I would ever use unless used in the following scenarios:
"That's it! You've cracked the case." (When referring to a previous piece of information or clue or input).
"That's it. I've had enough."
"That's it. I've been looking for it everywhere" (here I would use 'that's the one' instead).
Could you please provide an alternative of what this is supposed to mean? As this translation feels awfully unnatural to me. Is this a specific phenomenon that can't really be translated or is situational? As I would never say "That's it. She finally got her results" in this way?
