When Dora started to date Grisha, Kurfust was, for say less, not sure about that. He saw the tiger and even being so friendly as the german shepherd is, was jealous of "his little sister" . But when he he knoew the tiger better, notized that Grisha was a good person, just silent and with a "non intentional menacing expression" XD Kurt finally accepted him and actually is happy that Dora have him as boyfriend, because knows that he really loves and respects Dora and isn´t there only because her body, depite he have no trouble in admit that loves her curves . Also, with the time and the help of Marcos , Grisha becomed less serious and started to do pranks and smile more often, even pranking Kurfust too , as here, where Grisha is offering to carry Kurt to Lyn´s house before go to swim with Dora XD

Just a happy sketch that did when awoke x3
