The Somersault Turn of Promise! (約束のサマーソルトターン！ Yakusoku no Samāsoruto Tān!) is the fourth episode of season two of the Free! anime, and the sixteenth episode of the overall series. It aired on July 23, 2014.

Synopsis
With the prefectural approaching, Gou Matsuoka takes it upon herself to make balanced nutritional bento lunches for the team. Meanwhile, Sosuke Yamazaki recalls a promise that he had yet to ask of Rin Matsuoka since he left for Australia. Sosuke asks Rin what happened while he was away, and hears about how Haruka Nanase and the others helped him pick himself up.

When Gou's attempt at a nutritional bento proves to be effectively inedible, she compensates by putting together a tough training regime.

Later that night, Sosuke tells Rin he should give up on relays in order to focus on his dreams, but Rin states his determination to accomplish both. Despite having always preferred swimming individually, Sosuke asks to join Samezuka Academy's relay team in order to find something that he is missing, challenging Rin to a butterfly race to earn his spot. Admiring Sosuke's passion, Rin changes the way swimmers are selected for relays, asking for only those who are serious about being in a relay team to step forward.
