Wolfblood - Season 1 Episode 3 -

The school organizes an exhibition in which pupils show photographs of themselves with their families but Rhydian, who has none, feels left out. When the exhibition is vandalized he is the immediate suspect but Maddy gives him an alibi whilst suspecting the true culprit was Tom, angry that his father did not come to see his work. However Rhydian uses his special powers as a wolfblood to detect that the real vandal was Jimmy, a boy who has constantly taunted him and who is consequently excluded.
