Wembley had heard of Naomi from others, maybe even seen her in passing here and there - but he'd never interacted with her until he heard about her working on an antidote to the illness. He had the greenhouse now, after all, and could offer herbs and such from that to help with find a cure.

Fraggles don't have the best notion of personal space or property, so Wembley doesn't make his presence known with the latest delivery of ingredients, just heads in. Fortunately - perhaps - Wembley is also the noisy sort who mumbles and sings to himself as he moves around, even in this dire situation. So at least the odds of him startling Naomi are reduced.

Whether she knows he's there straightaway or not, he eventually tugs on her sleeve to get her attention, his other hand clutching a satchel filled with plants.
