Ive been looking into this phenomenon also. This same flight also leave Uvalde to make one stop at SAMMC military hospital before returning where it left from. Meanwhile, tail number "N383AM", appears to be working in and out of Uvalde until at least 7 PM
This story confirms 2 treated at SAMMC, so I am inclined to believe these 2 may have been transported by this helicopter that arrived so conveniently ahead of schedule.
