What I'm trying to get at is, what's the process involved of her doing this from an uninformed position?
To roughly outline it, she's required to:
1) Decide she wants to frame Ekko
2) Peruses other games to obtain something to frame him with
3) Stumbles upon a 3 year old game on NF, specifically
The problem with 2) and 3) is that while there's nothing strictly preventing anyone from doing this, Occam's Razor says it's more likely someone on the team just has prior knowledge, no?
