The thing about the nanny is, Buddy looks exactly like Jenn. Any random person seeing them at the zoo would recognize that. Then you have this woman with them pushing his stroller, holding his hand, carrying the bags like a pack mule, and hand feeding the kid. Not sure I would say, "yeah, that looks like a relative." The only relative we ever let do things for ours kids on a trip like that was a grandparent, and never even close to that much. I think people would assume Tim has two GFs/wives first, before thinking Planny is J's actual aunt or something.
