amantha receives an unexpected visit from her old friends, the Brockens, who would like Samantha to sit with their ten year old son, Merle, overnight. Samantha is a little wary to do so if only because Merle is a warlock who is just honing his powers, and she doesn't want to disrupt Darrin's mortal life by any further witchcraft. But Samantha agrees on the condition that Merle not use his powers while at the house, despite Merle needing to do his "homework", namely practicing his spells and incantations. Merle ends up being a very polite boy around Darrin, although in a slightly odd way. Half way through Merle's visit, Darrin does learn of Merle being a warlock after he catches Merle in the act. With that information out in the open, Samantha and Darrin can guide Merle in a more straightforward manner, including Darrin issuing the directive of no witchcraft whatsoever. Darrin may change his mind about Merle using his witchcraft when a burglar breaks into the house looking to steal the expensive necklace he knows Darrin is keeping for Larry. But convincing Merle of that change of heart for their personal safety may not be an easy task.
