Twillow

"I'm under your spell"

- Tara to Willow

Twillow is the femslash ship between Tara Maclay and Willow Rosenberg on the WB series Buffy the Vampire Slayer.

Canon
Willow and Tara met during a group session between the members of UC Sunnydale's Wicca group. Tara was quick to notice Willow appreciation and aptitude for real magic, however, the rest of the group did not share the same values on witchcraft.

Though the pair attended the Wiccan session, they did not properly meet until the Gentlemen arrived in Sunnydale and stole everyone's voices. With hopes that she and Willow could solve the issue, a now-mute Tara visited Willow's dormitory but is chased by the Gentlemen on the way. After hearing Tara violently knock on her door, Willow aided Tara in escaping the Gentlemen. The pair held hands and used their combined powers of telekinesis to levitate a vending machine and blocked the door from the Gentlemen. Once Tara and Willow's voices were returned, they discussed witchcraft and Tara tells Willow that she is special.

After this, Tara and Willow saw each other more regularly. They practiced spells in Tara's dorm room. During one session, they managed to float a rose, however, the spell went awry and spun out of control. The "magic sessions" the pair frequently had were intimate with hand-holding and arguably romantic gazes. Another time the pair meet up, they attempt to contact the goddess Thespia to detect demonic activity in the area. However, Tara sabotages the spell in an attempt to hide her presumed demonic heritage. Before the spell, Willow tells Tara how much she appreciates her friendship and their time together, suggesting deeper feelings regarding their relationship on both sides.
