They decide that if they bring Periwinkle to Queen Clarion, the queen will change the ruling and allow them to be together. Periwinkle meets Tinker Bell's friends, and Rosetta gifts her with a periwinkle flower, which she wraps in a sphere of frost to keep it from wilting. This machine creates a small cold zone that Periwinkle can stay in and keep cool while touring the warm parts of Pixie Hollow. Tinker Bell later returns with a machine designed to make 'snow' by grating a block of ice. Periwinkle thinks that this will be goodbye, but Tinker Bell privately lets her know that she has a plan, and tells her what she needs to do to make her plan work. Dewey takes Tinker Bell back to the border. They are rescued by Dewey riding his lynx Fiona, and Dewey decides that it really is too dangerous for Tinker Bell to remain. However, the campfire Tinker Bell made to keep herself warm damages the ice that Periwinkle's house is on, and the whole thing collapses. Tink and Peri heartbroken at the prospect of never seeing each other again. Periwinkle takes Tinker Bell on a tour of the woods, where Tink meets Peri's friends, bubbly Gliss and sarcastic Spike, and then to her home, where they discover that their tastes are virtually identical.

Dewey, unwilling to split up the sisters so soon, tells Periwinkle that although he was ordered to take Tink home, Lord Milori didn't say when. Shortly thereafter, Lord Milori arrived to speak to Dewey about his suspicions that a warm fairy had crossed into the Winter Woods and commanded Dewey to send any warm fairy who had crossed home. Tink meeting Gliss and Spike for the first time. There, they learn that the sparkle is a phenomenon that occurs when two fairies born of the same laugh draw close to each other, thus meaning Periwinkle and Tinker Bell are sisters! At this time Tinker Bell, looking for answers to the same question, comes into the library. Not knowing what could be causing the shimmer, she goes to ask Dewey, the keeper of fairy knowledge, about it at the Winter Woods library. Periwinkle ventures out to the border between Autumn and Winter to watch the animals crossing, where her wings start to sparkle.
