Season 3
The word Luiseach is first used by the Unknown Man after sunshine's sacrifice in the woods. He states that Sunshine is a Luiseach and thus cannot be harmed by Groundlings or Markons. After, Sunshine ponders what the word could mean, but ultimately isn't sure.

Season 4
When Nolan first arrives at Sunshine's house, he explains that she might be a Luiseach. In his words, a Luiseach is a person who can "simultaneously attract and repel dark energy." He says it's possible for Luiseach to still be around, but that they haven't been seen in a very long time. From an article he found, Nolan also explains that Luiseach are meant to have a Protector, and that Sunshine's could be Victoria.

After, Sunshine is dubious about being a Luiseach, but Nolan is sure that she is. In order to test her powers, he says that he, Sunshine, and Kat should visit his grandmother's house, which is allegedly haunted. Sunshine is initially hesitant to go, but eventually makes up her mind and convinces her mother to go along.
