Thor defeats the Doomstroyer by hitting it until its finite power supply runs out, and Balder locates Kelda's heart while also euthanizing all the remaining test subjects in Doom's lab:
Four scans from Thor #606.
The Asgardians head home, and, after two good issues, Balder's back to being a chump, as Loki is allowed to remain in Asgard.
Is that...green nail polish?
Cloning Loki. Yeah, best plan ever!
I'd be skeptical that this will come up in the "Siege" tie-in, so whose plot point is Gillen setting up here, I wonder? Fraction, most likely.
