Sif knew this Heimdall was a fake—an enchanted figure of sand—since he was so polite to her. They soon find the real Heimdall, who denies having opened Bifrost to her. Sif takes her new companions back to her place for a pizza party while she tracks down Aerndis. She finds the witch horribly aged and Aerndis explains she was the one who opened Bifrost for her. Sif wants more details of the berserker spell, but Aerndis reveals that she cast no spell—all Sif really wanted was permission to fight like a maniac. Meanwhile, the Black Lake (it was the monster, not anything within it) is terrorizing Broxton by threatening to pull it back into its own dimension. But the berserker Svip is also on a rampage, finding this new world more interesting than the one he left. She uses a bit of leftover lake monster to force Svip back into exile. She then realizes that what Aerndis said was true—all she wanted was license to unleash her fury and frustration, and she knows that this delusion that she alone could save Asgard was her weakness….
Epilogue: a calmer, more controlled Sif joins in a snowball fight with the children of Broxton….
