Telepathy is the supernatural talent to share one's thoughts, feelings or memories, or sense those of others.
In Teen Wolf, two types of supernatural beings, and two types of beings are capable of telepathy.
A werewolf can initiate telepathy using their mind melding with their claws. Banshees apparently can utilize the talent naturally. The being designated as Master of the Kanima has this power over its kanima servant.
Dr. Gabriel Valack is also telepathic, being able to share, bestow psychic visions upon others. He may also be able to read minds as he corrected Alan Deaton, whom he'd only just met, that he wanted to know about Kate Argent, in response to Alan's wish for his knowledge on South American lore.
