Will we finally learn what secrets Geillis is harboring?

The accused witch (Lotte Verbeek) has hinted at her shady past previously, but now that she’s forced to stand trial, those secrets may come to light on Saturday’s episode of Outlander.

“They say I’m a witch,” Geillis says in a new character spot provided exclusively to PEOPLE.

“Are you?” asks Claire (Caitriona Balfe).

Geillis answers, “I believe there are powers beyond what we can see and hear and touch.”

What those powers are, however, she doesn’t explain.

On last week’s episode, Claire accused Geillis of poisoning her husband so she could run away with Dougal (Graham McTavish), her lover and the father of her unborn child.

But before the happy couple could get together, Colum (Gary Lewis) kicked Dougal out of Castle Leoch and sent him away with Jamie (Sam Heughan), leaving both Claire and Geillis alone – and easy prey for Laoghaire (Nell Hudson), who took the opportunity to falsely accuse the ladies of witchcraft.

As PEOPLE previously reported, two clips released on Wednesday show the beginning moments of how those accusations will play out when Outlander airs Saturday at 9 p.m. ET on Starz.
