Gill left Monster High because his parents doesn't believe his people should be seen with Lagoona's so they sent him to boarding school but in the Fright On he came back because he loved Lagoona so much
It was of course; because his parents could not see the 愛 blossoming between Gil and Lagoona and never breaking the tradition of "Freshies" not being able to be seen with Gil himself and his 'racist' parents: "Salties." This little crack in the road was nothing though, because as seen in "Fright On!" and a few webisodes after Back to Ghoul, Lagoona is reunited with her (perfect-for-her) boyfriend! This proves that with 愛 that is as true and pure as Lagoona and Gil's; nothing can stand in their way!❤ L❤ts ❤' L❤ve: BrrrFan
