After all we have seen in the series, I would simply guess as a child Kelly is probably the same as Sean Renard (Half Zauberbiest/Half human), since not every member of a Grimm family also becomes a Grimm (see season 2 episode Bad Teeth), so if he hasn´t the potential to become a Grimm, he would be like Sean Renard and if he would become a Grimm like his father, he would be like Sean Renard with Nick´s Grimm powers (Nick gained this powers with at age 29, since males show this powers later).

But logically in any case he wouldn´t be able to use telekinesis and other powers (Illusions etc.), since Sean Renard, who is also Half-Zauberbiest couldn´t use this powers, either (Only Full Hexenbiests/Zauberbiests have this powers). In my understanding Grimm´s are simply humans, who have special abilities to fight Wesen (a sort of Anti-Wesen) and that´s probably also the reason, why most wesen powers and potions work differently on them (Cracher-Mortel, Jinnamaru Xunte, Verfluchte Zwillingsschwester etc.) and in any way his grimm side has nothing to do with Kelly´s hexenbiest/zauberbiest potential, since Grimms aren´t able to use such powers. His Grimm blood possible could even destroy his zauberbiest side (like Nick has done it with Adalind, once).

In my understanding the only way to maybe become, what many here on this wiki describe (Grimm with Hexenbiest/Zauberbiest powers) would be a human from a Grimm family (George Kessler for example), who has a non-activated "grimm gene", becoming a Hexenbiest/Zauberbiest like Juliette through the Verfluchte Zwillingsschwester potion or another way (since Henrietta and Adalind knew from other "created Hexenbiests") and getting a child with another Hexenbiest/Zauberbiest. This child would be 100% Hexenbiest/Zauberbiest, but also theoretically has the potential to become a Grimm. Such a child would be definitly the strongest being in this series (something like Conrad Bonaparte with Grimm powers).
