I don't think I qualify as an expert, but here are my thoughts:
I don't find that episcias do well outside, unless you have a moderately warm (not too too hot) and very humid climate. If they're outside, they'd need even moisture, no soggy soil, and brightish light with no sun at all. Especially the pink variegated ones need a terrarium, some of the other ones do as well. You may see the plant drop leaves if they go from the heat and humidity of a greenhouse to your home. You may also want to look for spider mites.
