Now... a logical person would see a new arrival and introduce themselves. Probably strike up a conversation and get to know them. Normal stuff. Sensible stuff. Probably any other day, Kenzi would have done that normal stuff.

But it is really, really, REALLY boring here sometimes and she decides to follow this chick instead. Nonchalantly at first, like she just happens to be coincidentally walking in the same general direction, but then she goes into exaggerated stealth mode like the vigilante super hero she truly is! She might have just rolled behind a hedge just now...

Totally normal.
