'Watson' Goes Dark in a Game-Changing Finale

John (Morris Chestnut) may have discovered that Moriarty (Randall Park) is still alive in part one of the Watson finale, but that didn't give him a lot of ideas about what to do with the supervillain in the concluding hour of Season 1. Before John could figure out what to do about his nemesis and his best friend's killer, he and the team had to figure out which Croft twin (Peter Mark Kendall) to save. That was no easy task, considering both twins were an integral part of the team, and there were emotional attachments on all sides.

Ultimately, it came down to a coin toss, and Adam won. He was given a single dose of the anti-viral and brought out of his coma so the team could start working on backup ideas to save Stephens as well before the virus caused irreversible brain damage. The team needed to use everything at their disposal to come up with a solution, but that was made more complicated when Shinwell (Ritchie Coster) revealed Moriarty had also poisoned him, and Ingrid (Eve Harlow) was struggling with which side of the fence she wanted to be on. Was it worth trying to redeem herself after she destroyed the samples that could have saved both twins, or was it better to just make the jump and join Moriarty on his mission? The evil professor at least seemed to appreciate her talents.

It would take every member of the team to pull of a medical miracle and finally give John the upper hand, but what he decided to do with it was pretty damn shocking.
