He's Friends With Dumbledore
While staying with his great aunt in England, he meets Albus Dumbledore in late 1898. Even though they have strikingly different personalities, they establish a strong friendship. Together, they have two goals: to seek out the Deathly Hallows and to abolish the Statute of Secrecy. It was revealed by J.K. Rowling during a tour in 2007 that Albus actually harbored romantic feelings for Gellert, referring to his love as his "great tragedy."
