There is no shortage of mommy issues on Grimm. Whether it is some twisted Aswang tradition of consuming a son’s firstborn, or finding out your mother isn’t dead like you thought, the writers really know how to contort the notion of a mother’s love. “Lost Boys” takes us on a sad and perplexing journey with four orphaned children on the run, desperately seeking a mother’s love, even if the love isn’t given willingly. Buried in the subset of “Lost Boys” lies the ongoing saga of the Wesen uprising and the meaning of “Occultatum Libera” becomes much more significant.
