When ABC and Disney snatched up the Marvel universe, you knew it would lead to more marketing of all its related major franchise properties. But tonight’s move may have been less expected. In an obvious yet surprising move to bring Disney Channel viewers to ABC and its televised, ongoing Marvel’s Agents of S.H.I.E.L.D. series, the network has cast Dove Cameron, its standout young Disney Channel star from both Liv and Maddie (a sitcom where she played both roles) and the Descendants telemovies (where she stars Maleficent’s daughter Mal), in a guest role as Ruby, a rebellious young daughter of a military mom poised to hunt and capture the agents of S.H.I.E.L.D., who in this midseason return are back in their own time – but hunted as fugitives.
