P5R Sae Interrogation?

[Echō]

Potentially a dumb question.. I'm ONLY at 7/10 currently.. (First playthrough btw) I DID look up endings but am also confused.. To get the true ending you can't sell out your friends... but Sae (where im at) just currently told me "Makoto is your new member" but I never told her that specifically... To best summarize my thoughts... To get true ending is Joker story "giving Sae" what she wants or do I through dialouge have to actively snitch?

To add a little more context ^ I haven't been saying anything unless its forced dialogue options.. or I'm being extremely vague with her

You don't have to worry so much; the ending choices are isolated dialogue choices, much further into the game than you are. Any dialogue options you pick now will have no effect on it. They will make it abundantly clear where the important choices are.

if i remember correctly (havent played P5R in a while because im finishing P3R) the ending changing questions are pretty layed out as "ending changing" its either a prompt or just really easy to tell, like "All my friends are phantom thieves" or sum ♥♥♥♥♥♥♥♥ like that.
