Sonic and Princess Elise the Third had a very close relationship with each other, and they shared a strong bond. Mephiles was aware of this, and decided to take advantage of it, so he killed Sonic which caused Elise to cry, which freed Iblis. Elise later revived Sonic with the Chaos Emeralds. After the defeat of Solaris, Sonic and Elise found Solaris in its frail, core form. She theorized that by putting out the flame now, Solaris would have never existed, which would make it so that she would never have met Sonic. Elise nearly broke down and declared that she did not care what happened to the world, but Sonic simply reminded her to smile, convincing her to be brave and blow out Solaris. This event instantly resulted in a time reboot. In the aftermath, Sonic watched the Festival of the Sun in the distance as Elise sensed something familiar about his presence.
