This has been bugging me and some other attentive fans as well. It's specially weird because just months ago, in the War Scrolls mini, Billy and Teddy were still living in the loft from New Avengers. It was Death's Head that seemingly changed their location, and we can definitely tie this to the writer, since she is currently writing Strikeforce as well. The fact that there wasn't just any explanation at all makes me think that Tini simply made a mistake when she described the apartment to the artists, or Kei Zama made a mistake by assuming how the apartment was supposed to look like without doing proper research in other books, and now German Peralta simply followed that mistake. Unless this gets addressed on page, I'm gonna go with this explanation and hope that some future artist brings the original posh design back. LOL
This is definitely Ghost (I mean, the solicit even hints at that). I'm curious to see how they will incorporate him (I'm assuming it's still a dude, but who knows with synergy these day) into the story.
