Thanks to Thomas for the heads up.
Ryan will step into the role of Gwendolyn Hayes, who (surprise!) has very close ties to none other than titular hero, Angus MacGyver (Lucas Till). Mac knows a lot of things — like saving the world with the gelled sodium polyacrylate found in disposable diapers, as he did in the Season 4 premiere — but the fact that he has an aunt comes as a big shock for him.
