Biography
In the town of Storybrooke, Will Scarlet is seen meeting Ashley Boyd and Leroy walking into Granny's Diner during a storm and making himself a cup of tea. When he is doing so, however, there is an earth-tremor and the White Rabbit appears via portal, telling Will that Alice needs his help.

Will travels to another land with the White Rabbit in order to break into the asylum Alice is currently confined to. He knocks out some guards and makes it to her cell, telling her that Cyrus, her true love, is still alive and she needs to come with him to Wonderland. With each other's help, Alice and Will escape the asylum and go down a portal created by the White Rabbit. Upon returning to Wonderland, the two of them become stuck in the mallowmarsh and have to use fire-breathing dragonflies in order to toast the surface and use this segment as a platform to escape. They soon realize that the Rabbit is gone, after being disappointed to learn that he didn't actually see Cyrus in the Mad Hatter's house, but in fact heard it from the untrustworthy Dormouse. The Knave does not wish to go any further, but Alice offers to pay him with the three wishes she received from Cyrus should he help her find him.

Alice removes her shoes in order to climb a tree, thus gaining a view of the Hatter's house, but Will decides to steal her shoes and run away, as the wishes are hidden in the heel. When Alice is attacked by the Cheshire Cat however, Will steps on his tail and throws some mushroom into his mouth, which shrinks him. Alice tells him that it was silly to steal the wishes as they have to be granted by a genie in order to come true, and Will proceeds to accompany Alice to the Hatter's house. When they arrive, they find no sign of Cyrus, but Alice discovers his magical necklace and takes this to mean that he's still alive somewhere. When the White Rabbit shows up again, he, Alice and a reluctant Will continue to journey through Wonderland in order to rescue Cyrus.

Will wakes up to Alice practicing with her sword, telling the Knave that she has a plan to rescue Cyrus: first, find his bottle (which she says is buried in Mimsy Meadows), and then wish for something minor, and he shall appear to grant said wish. They go to carry this plan out, leaving the White Rabbit behind them, but Will is horrified to discover that the way to Mimsy Meadows is across a large lake as he is afraid of water and unable to swim. Alice suggests that they call upon the lake's fairy, something which Will is also hesitant about, but eventually, after the two of them clap a summons, the fairy Silvermist arrives. Upon seeing the Knave, she slaps him multiple times, the two of them clearly having a bad history.

She agrees to fly the two of them across the lake using her magic, but as she's doing so, she lets Will drop into the water. Alice then jumps in to save him and the two of them find themselves on a small island in the middle of the lake. When the island bucks them off, Alice realizes that it's not an island at all, but a large turtle. By threatening it with her sword, Alice convinces it to sail them to Mimsy Meadows, and Will sits effortlessly on the turtle's back as it swims across the lake. After another run in with Silvermist where Will ends up apologizing for whatever he did to her, they arrive where the bottle is supposed to be buried, they see that the evil wizard Jafar is already digging. At this point, Alice reveals that the bottle was never buried there and that she merely wanted to know who she's up against by letting word spread of the bottle's supposed whereabouts. However, when she leads Will to where the bottle is really buried, she discovers that it has already been dug up, which leads her and Will to think Cyrus has moved on.

But later, an enchanted paper swan with a message from Cyrus arrives for Alice, and now filled with hope, she sends a message back, telling her true love that she's coming for him.
