Time Lapse:
Three years have passed. Just as he predicted, Soundwave fell back under the control of the Virus. Program returned, stronger than ever, and Axle began to lose hope that the Kindling would ever have a leader to start their revolution.
Meanwhile, in the Cascades, Mason has built himself a home in the abandoned shed. Fully furnished with the money he had. He became quite fond of his new life, and slowly began to accept that he might never see his sister again. He moved on, and focused his energy on his new responsibilities. To Vibes' delight, he brought up goats and chickens to his new home. Isamu was not forgotten, but everyone was surprised to see him become an excellent mouser. (And even lose some weight!) Mason also kept in touch with his parents, who struggled through a long period of time in trying to accept how little could be done to find Audrey. Slowly, they too moved on with their lives, and were happy to be reunited with their son. Mason sometimes returned to his childhood home to catch up with his parents, and share memories.
Melody spent a lot of time worrying about Optimus. It was a given, considering he had a war to fight. He visited when he could, and promised that when everything was done, they would settle down. Perhaps even back on Cybertron.
The other Autobots eventually forgot about the twins, and continued their fight against the Decepticons. Optimus was reluctant to tell Melody about their encounters with Soundwave, however. He obviously wasn't the same Mech she had once known.
And while life and war continued, Audrey remained in stasis.
Now, the war seems to be over. The Autobots have taken over the Decepticon ship and are ready to begin rebuilding civilization on Cybertron. But the story isn't over yet…
