Zohar is an unwitting medium
Zohar subconsciously summoned Tehila's spirit from the land of the dead into Irena so she'll defend her from Meir not taking a "no" for an answer in the nastily literal sense (she'd also have to have powers of clairvoyance to know she'll even need that kinda help).- After her army service, she'll join the division of the Shin Bet (Israel's internal security service) dealing with supernatural threats and will learn how to consciously summon Tehila's or others' spirits to either obtain knowledge from them or to use them as a source of superpowers.
