It's been a while since we've seen Power Pack's Jack and Katie. Have they aged some? And will this be the complete group? Because Alex went off with Reed Richards and his family at the end of "Secret Wars."
Moss: Yeah, they'll have aged some, but not much. After some time with the Loners and Avengers Academy, Julie has decided to focus on a normal education, so she's enrolled at Empire State University in New York, and this story sees Jack and Katie coming to visit her. So, yeah, no Alex here, but the story does briefly deal with his absence. Writer John Allison (of the tremendously fun "Giant Days" series) and artist Rosi Kampe are handling this story, and they've done a great job with it -- staying true to the voice of the characters and the original series, but with 2016 very much in mind.
