Great show. Loved it more than the first. I just had a thought. Will done puked up demo-dog larvae at the end of season one. He specifically mentions he did it the one time. So where did those others come from? It appears the egg needs to incubate for a time in a living host. Does that mean there are other hosts out there like Will? Are they too shadow possessed? Or did they just hop over from the Upside Dowm?
