Recap: Transformers Prime S 2 E 21 Alpha Omega
Coming directly off the previous episode, Dreadwing wants to counterattack the Autobots for having lost the star saber, but Megatron clearly points out that the star saber has rendered any attack meaningless for the cons.
While Dreadwing then points out that they have a prime relic as well in the Forge of Solus Prime
, Megatron also points out that they need a prime to use it. This then gives him an idea on how to get the edge on the autobots.
Meanwhile Optimus is listening to an age old message from Alpha Trion. It's revealed that he sent all the relics to earth.
