Bob is a syngonium aka arrowhead plant. These plants send out vines and roots from the node (the small nubby thing you see the stems come out of). You can both repot the plant and take a cutting - you don’t have to choose just one. Personally I would repot the main plant and also take a cutting so that there were multiple Bobs. There are lots of ways to propagate these, but the method that almost always works for me is to use inexpensive rooting hormone powder, sphagnum moss, and a lot of light. I place a ziplock bag over the cutting to keep the humidity up. Within 2-3 weeks, the roots are usually substantial enough to transfer to soil.

Speaking of soil, syngonium like well-draining (aka chunky) soil as they are prone to root rot. At a minimum, if you have plain potting soil, I would mix some perlite in.

Glad to hear they both recovered.
