I wonder what her part in the defeat of skull-face might be. Maybe Nick and baby Kelly and Trubel will combine their Grimm powers to vanquish skull-face. There should be a Grimm ending to skull-face not just by Nick's hands but a concerted effort of Grimms.

I can feel that. I was wondering when they would shine more light on baby Kelly and his powers.

It's a shame that the series is at the end for them to mention him with respect to skull face wanting him too. I wish they had continued to do something with Kelly...even if it was from time to time a mischievous act here and there to remind the audience that he is also special.
