The orange “telephone receivers” are cellular destabilizers. They were first seen in “Day of the Dork”, where Gareth (the guy holding Cass) used them against were-poodle Keris. I added them into the establishing shot of the advanced equipment room on a whim, presuming that Jen would have a problem with a teenager creating a portable device that could literally break apart living tissue. (It also helps explain why Gareth is working with Ken in the first place.) On this page, Ken originally subdued Cass with a taser he kept in his pocket. I thought that idea was too “normal”, and when I realized that the destabilizers were right there on the shelf, I drew the page to show Ken moving into the room, where he could reach for them quickly.
