The Questers are worried about Gwen. She seems a little testy and they're convinced they know why: She misses someone her own size! So, they set out to find her a playmate and Elspeth ends up creating a doll that comes to life. Gwen and her date have a whirlwind romance - laughing on the beach, riding a toy horse, etc. - that makes Roderick terribly jealous so he fights the doll in a duel and loses. Now, he's the one in a testy mood!
