Man, I haven't done this in months, Story Fam!
Cammy to Chun-Li: "Thank you for all of your help against Shadaloo. I'm sure that we'll fight together again someday."
Thoughts: I'm glad Capcom still recognizes their friendship. I'm glad that there is still a mutual respect to each other. And I'm glad Cammy is showing gratitude to Chun-Li, as I'm sure Chun-Li would feel the same. With Chun-Li on the retirement side, and Cammy still on the job, it would make sense that these two's paths wouldn't cross as frequently anymore: Cammy is off saving the world, while Chun-Li is now a teacher. However, i feel this quote does affirm that Cammy believes Chun-Li has her back, no matter what. So if there comes a time when Cammy needs to call upon her fighting bestie, I'm sure that if Chun-Li would be right there to help her.
Lily to Chun-Li: "You're strong, and always fight for what's right. The spirits say so."
Thoughts: I think this can be simplified that Lily's guardian spirits can sense the goodness of Chun-Li's heart through combat. But here are some alternative takes to her win quote.
Maybe the spirits have been alive longer than Lily, dating all the way back to SF2 when Chun and T-Hawk were in the same arena. Maybe those same spirits are just passing down what they've seen and felt with Chun-Li back then and reaffirming that her heart hasn't changed in 6.
Lastly, and this one may feel a little out there and a little existential, but hear me out. Lily seems to be a very spiritual girl. She has deep connection to the wind spirit and those of her land. But who's to say that she can't also feel a presence for other spirits as well? Like say, Chun-Li's father who has been watching Chun-Li grow up this whole time. Maybe Lily's win quote is his way of passing a message through Lily to tell Chun-Li that he is proud of what she's accomplished and become. (Again, a little out there, but an alternate interesting take)
