: I think it's safe to assume Cortana has broadcast and reached out to
: thousands of AI prior to her actual appearance on Infinity, I wonder if
: she has had private communication with Roland or he was at least aware of
: her plan, and I he is keeping it secret. Lots of potential with Roland.

My understanding is for whatever reason she couldn't find Infinity, and by extension Roland, until the very end.

(why she couldn't is something I'm very interested in learning about... there doesn't seem to be any narrative reason for it unless it's going to come into play later.)
