Gasteria "Flow" pup

I have a coworker that got a windowsill succulent .... and over time it never really died.  It's a Gasteria "flow" and the internet tells me that it's a hybrid between a gasteria and aloe. 
"Botanical name: Gasteria Verrucosa x Aloe Hybrid PPAF" ... something like that.

Of course, I had to tend to it .... and guess what comes up?  A tiny pup detaches too easily, and now I'm stuck holding a piece of this plant.

Not much to it.  I sort of origami folded a paper swaddle for it
Taped it together with .... tape.  Wetted the paper towel from time to time

Over time, the root turned from nothing to this:

Those roots are more durable than they appear but don't risk breakage

Now later it looks like this:

Nice and plump leaves
