There is no public connection to the CNs anymore. No mentions post-graduation, no five jack-o lanterns, no pointing out in Reddit memes. Hitomi Chris was undebuted so early on that she might not even exist in most people's collective consciousness.
Meanwhile, most of Aloe's statements are still available online, and there is a thread for you to see what she is up to nowadays. Do we know she talks to her former genmates? No, but it is likely, she might even meet them in person, and unlike the CN branches, she could meet most other holos.
