If you're the son of a Grimm and a hexenbiest, you can expect to be the focal point of a whole lot of weird. For little baby Kelly, his first foray into the supernatural will happen this spring.

Adalind's (Claire Coffee) daughter started showing signs of telekinesis while still in the womb, so by all accounts, her half-brother is a bit of a late bloomer. Although he is still in diapers, Kelly will start to show some "other worldly tendencies" over the next few weeks, according to TV Line.

Don't expect Nick's (David Giuntoli) son to mimic his big sis, however. Diana is ¾ hexenbiest while Adalind's other child is half Grimm. In other words, don't expect Kelly to suddenly start aging at a break-neck speed.

"He's too young," executive producer James Kouf said of Kelly's powers, according to TV Line. "He's not even eating solid food yet!"

Coming up on Grimm, a mysterious lake side death will pique Nick's interest in "A Reptile Dysfunction" (see a preview below), a dangerous ancient wesen ritual will spark a rash of killings in "Star-Crossed," and "Map of the Seven Knights" will dive back into the seven keys mystery ahead of the 100th episode.

Grimm airs Fridays at 9 p.m. ET on NBC.
