Good job ... pretty Episcia! I haven't grown Episcia's in a few years and don't really have a lot of experience with them but I used to just sever the little stolon from the mother plant and pot it up in it's own little container. You can also lay the little stolons onto soil where they will take root and then detach the main stem from the mother plant.. I'm not sure about water rooting, I've never tried that but they readily take root in a well draining potting medium.
I copied the following from the VioletBarn:

Because episcias freely produce stolons, which bear small plantlets at their tips, propagation is extremely easly. Keep the center four leaves of these plantlets, and keep no more than 1/2" of the stolon. Also remove any small buds or smaller plantlets from the one being rooted. If the plantlet's leaves are too large, the ends of these can be removed. Press the stolon and its base into moistened soil (firmly) and place in a closed, transparent, container. Rooted plants can be removed from the container in three weeks--or you can continue to grow them there if you need the extra humidity.
Once they begin to grow, it's best to remove the small, developing stolons, to allow the plant to more quickly, and fully, develop. After the main stem gets thicker and stronger, and the plant matures, it will bloom. At this point, we pot it into a larger pot, or basket, and allow the stolons to grow. These, too, will eventually produce blooms and stolons. Episcias grow very quickly, and can look "weedy" if unattended, so don't be afraid to remove excess stolons. When well grown, they can be some of the most colorful and rewarding plants in your collection.
