I can relate regarding the hospital phase; personally, I just acted as if I’d seen them all. Lol.
As for the redhead—or at least that’s how I saw it—the flirting is really quick; there’s no time to get attached. It’s very brief—just a couple of lines exchanged—so not enough to form an emotional bond, but enough to spark interest or make her memorable. That’s why I concluded there might be a plot twist.
