I didnt know we knew the Ice ladies cell phone number and were able to do a call afterwards. Seriously we have no idea what the time and place should be, the logisitics are impossible, and like we are supposed to convince the entire sect of the unproven worth of another faction just so we can chat.
Like we can do this in the second option because her helping shuts up the voices in the sect who might hurt her (since she actively helps us) and logistically its easy since its just staying after the fight.
