Cool. Cool, cool, cool.
Love the Jackal, love the clones (a bit more in theory than execution), love Kaine and Ben. This has entertaining stamped all over for me.
I've been expecting Marvel editorial to demand Gwen be brought back for a while (hence Spider-Gwen, which really paid off), so as long as we get Kaine and Ben back I'm okay with it. Though I do hope Gwen-clone goes. With that in mind, Slott hasn't been too kind to Gwen colnes in the past.
