Okay..

ok Sonic and Sally had two teenage twins, Sonia and Manik. they were sixteen. but Sonic did something to alter the timeline sa pamamagitan ng mistake, causing Shadow to be the king and married to Sally, resulting in Sonia and Manik not existing. Lara-Su fought off King Shadow and Sonic and Sally reunited. but the timeline couldn't be changed back to its normal state so Sally and Sonic had to get remarried and, once again, have Sonia and Manik. so Lara-Su went from being their best friend to being their babysitter

knukles says theres something wrong with the future because of shadows rule so king sonic goes to fix it but he (not on purpose)changes the timeline erasing his 12 taon old kid from history knowing this he defeats shadow and brings the idea of kids to sally
