When Sam realises that she doesn't have a present for Wanda's surprise 70th birthday party, she freaks out - she wants the perfect present for her grandmother. She doesn't want to make a mistake about this one, so she asks for the power to read people's minds - that way, she'll know exactly what Wanda wants! However, things get out of control and Wanda's surprise party risks turning into a disaster... and the half power means that Sam can't help saying things out loud.
