Loose end tied up

A while back I did a series of loose ends that have occurred in various TV shows. One such example was the fate of nefarious tycoon Ian (Dean Conrad) Quinn in Marvel's Agents of S. H. I. E. L. D last seen on the run in the Season 1 finale. Now in the most recent episode shown on British  we see Quinn being consumed by the super substance Gravitonium. This scene was done in a flash back with the caption 4 years ago. The show is now in it's fifth season.
