User blog comment:Demileto/Is Lincoln Campbell really an alias for Thomas Ward?/@comment-26905421-20150819063409

Although I haven't been able to find said trailer anywhere, there was apparently one released today for s3 of AoS, and Ward was said to have been Hellfire. Now, assume your theory is correct (and I hope to hell it is), that would mean that Grant has the Inhuman gene in him. In the s2 finale, the last "scene" was a case of the crystals that make Terrigenesis possible open underwater, and the crystals were dissolving into the sea, the fish were ingesting said water, then being caught by fisherman, until, long process later, they wind up on the shelves of countless grocery stores (or other stores) in the form of fish oil pills for anybody to ingest.

Ward's Terrigenesis could have been activated by him ingesting a few of these pills...
