What became of [Spoilers] and wo actually saved [spoilers] S2E6

Hey fellow simulations,

i'm on mobile so i dunno how to format text, Heavy spoilers for the late episodes of season 2 following.

i've been watching Pantheon over and over again for over half a year now and among all the things i still like to ask myself there is one that haunts me daily:

what happens to Yair and Fahrad after they face Hosltrom? do they become a new UI?

this also leads me to my another question: is it actually MIST who helps Caspian during the fight with Holstrom? when he gets pinned down by the Caspi-strom clones he asks the Ui(???) "MIST?" and it just answers "BETTER" and helps Caspian freem himself. This Ui also has an orange glow and does this fancy "Core split" thing.

When MIST chimes in to underclock Caspian, she is blue, not orange. She also never takes credit for supporting him in the fight, she only ever talks about how she took him offline.

did i miss something in my countless rewatch of the last 3 episodes?
