Willow’s character then has to atone for what she has done. Firstly, she has to change her attitudes (and beliefs) towards magic. Secondly, she has to accept responsibility for the fact that she caused pain to her friends (and enemies). Thirdly, she has to face up to the fact that Tara is dead. Giles is able to help with the first of these: by taking Willow to a coven where she can work towards reconnecting with the “true essence of magic“. This is achieved by helping Willow connect with nature, and in doing so, become closer to “Mother Earth” (and all things good). Willow has a harder time dealing with the second: as she’s worried that the Scoobie Gang won’t want to know her (after what she did to them).
Upon returning to Sunnydale, Willow does not have time to see whether or not she’s fully recovered, as her magic is required straight away: Willow casts her “Demonic Energy” locator spell (with assistance from Anya), involving candles and the scattering of powder on a map, to help her track down a demon (that’s been flaying its victims). The Scoobie Gang initially suspect that Willow may be responsible for the flaying (because that’s what she did to Warren), although Dawn eventually discovers another possibility: a demon. It is only after encountering this demon (and chatting with Anya), that the Scoobie Gang realise that something else is a foot: as Anya can see Willow, but the rest of the Scoobie Gang can’t. It turns out that Willow has not yet fully recovered: she was so afraid of her friends rejecting her, that she managed to subconsciously cast a spell, whereby they were unable to see each other. Once the spell is reversed, an important indication of friendship occurs: Buffy allows Willow to take energy from her, so that Willow may magically heal herself (from the injuries the demon inflicted).
