Summer arrived, but Cyrus did not return to Britain, choosing instead to remain at Durmstrang. She wanted to use those two months to absorb as much Dark Magic knowledge as possible, with Grindelwald himself guiding her from the side.
Kate had successfully graduated and gone to work at Lupin's alchemy company. Lupin needed to process a large number of werewolf employment applications, and Kate assisted him while also managing the production of alchemical goods. The twins also spent their summer vacation interning there, frequently sending Cyrus all sorts of novel alchemical products.
Sirius spent his free time wandering around Privet Drive with Harry. As long as Harry returned to sleep there at night, it would not break the protective charm of love his mother had cast. During this period, Cyrus went back to attend Regulus's funeral, which was attended only by Sirius, Lupin, and Dumbledore. Even so, he was quite content; the matter of Voldemort's Horcruxes could not become public knowledge, as that was the crucial information for defeating him.
