I thumbed through it on Wednesday but didn't even notice that panel. What all happened? Worth picking up next week?
In terms of the FF there's a scene with Ben and Johnny wondering if the FF are still relevant in today's world and they fire a flare in the air. At the end Franklin and Valeria and riding on space scooters or something and exploring a universe and there's a hint that they may be coming back to the "616" reality. Reed is mentioned but not shown.
The rest of the book is various threads that will lead into many of the Marvel Legacy books. The main plot centers around a Celestial in prehistoric times that was buried by early versions of the Iron Fist, Black Panther, Ghost Rider, a Phoenix, Starbrand, and Odin. I hate these types of revisions.
Is it worth it? I'd say no.
