Fukuin-Lion describes how Shannon, her only friend, doesn't step in to defend her as she's getting bullied. Just like how Ange's stakes never stepped in to help her.

And then Lion says "She'll show me how things are done, but she'll never steal my jobs from me."

in other words, she doesn't ever physically interact with things, huh

so Shannon is Lion's imaginary friend

This "Shannon" we're seeing isn't really there, and the Shannon from episodes 1 to 6 is apparently just Lion, grown up, pretending to be this imaginary friend...
