“The Subway” but it’s season 4 and 5 Basira and Daisy. Especially this section in particular:

“Made you the villain, evil for just moving on.” - Basira being upset that Daisy wanted to move on from being an Avatar of Hunt (or more specifically being her protector) at the cost of her own life.

“I see your shadow. I see it even with the lights off.” - Basira chasing Daisy’s monstrous form through the apocalypse.

“I made a promise” - Basira shooting Daisy because she promised too.

“If in four months this feeling ain’t gone, well, fuck this city. I’m movin’ to Saskatchewan.” - Basira helping to stop the apocalypse and having to move on with her life without Daisy afterwards.
