Some BBC viewers are claiming the latest episode of is an "incredibly frustrating" watch as . The 20-year-old actress, who starred as the main companion to 's Doctor last season, appeared in 'Lucky Days', portraying the love interest of podcaster and antagonist Conrad Clark (played by Jonah Hauer-King).

The latest instalment of Doctor Who aired on BBC One on Saturday (May 3), opening with the Fifteenth Doctor and (Varada Sethu) landing in 2007 England. There, they meet a younger version of Conrad, who grew up to become obsessed with the Doctor and his TARDIS.

He invites her onto his podcast, and the pair begin dating. While Ruby believes their relationship is real, Conrad only began a relationship with her so that he could use her to expose UNIT (an international military organisation) for spreading lies about aliens, monsters, and wasting taxpayers money.

Eventually, the antagonist is reprimanded, with the Doctor swooping in to give him a talking to for the way he treated Ruby.
