Becca and Seth are by their favorite spot when they were growing up which is a lake.
When a massive fire breaks out on the lake, innocent lives were on that lake humans and mutants who can live together in peace and harmony.
When the innocent were stranded on the lake Seth decides to go save everyone out on the lake.
Becca tries to stop Seth before he tries to get himself killed just by getting in the water where the flames were.
Becca looks at her twin brother worriedly. "Seth please don't leave me."
Seth looks at his one chance to redeem himself after everything he has done to hurt mutants. "I have to. I'm sorry Bec." Seth jumps into the lake where the flames have gotten worse.
"SETH NOOO!" Becca yells.
You rush into Becca's room where she believes that all of this is actually happening when it's only a vision.
