By far the most advanced storyline and continuous dramatic changes in this season has made it the best. So many twists and turns that still include prior storylines. Great inclusions lime this have lead to a great culmination of future potential for this series.
Fan spoilers here's. The gravitonium is actually an obelisk, holding some warrior that's trapped inside. He sucked up everyone he could grab because the portal is always open. Quake is the only one that can manipulate the gravitonium just like all other obelisks is because of her power. It's not the gravitonium, it's the power of the person on the other side that's a super ultra destroyer of worlds... her power will just release all of the trapped people still in whatever that portal or however they are inside that gravitonium. Would be coolish
