Mini-update: Spider-Island: The Amazing Spider-Girl #2 has been added to the site. Firestar appears and gets a line, and Cloak and Dagger show up in the background as well. All three show up on only 1 page, so not a major appearance by any means.
The footnote seen in the featured image above references Amazing Spider-Man #667, which is when the Bryant Park battle begins, but the battle being over and the reference to Mayor Jameson means the scene has to line up with Amazing Spider-Man #668 instead. The issue has been added to Limbo – Part 4 Phase Five.
What complicates this appearance is that Dagger should be gone and kidnapped by Mister Negative by now, based on the Spider-Island: Cloak and Dagger mini-series.
However, there is a gap between the first and second issues, so it’s possible Dagger went to class at the end of the first issue, then returned to help finish the Bryant Park battle, which goes on into the next morning, at which point she’s seen here. Then Dagger leaves again for her study session with Patrick at the start of issue 2, where the rest of Cloak and Dagger’s mini-series plays out. It’s not the most elegant solution but it accommodates all of their appearances in Spider-Island so far.
