not a whole lot happened. It appears that the Fallen from 1 million bc was infected with the insects that we saw Strange and BP deal with last issue. Eson attempted to communicate with (She?) Hulk...she is then teleported to wherever GR is and they have a fight....the other "normal" Celestials appear to have succumbed to the same insect infestation....but not the Final Host. They seem to be ready for a purge. Eson is beheaded. How and to what end Loki is involved is not yet clear.
