Best Friends Thomas the Tank Engine & Friends : Season 12 Episode 20

Neville informs Thomas and Percy that the brass band is coming for a special concert. Thomas suggests that if Percy wants to collect the band then he should go to the washdown, but while Percy is away the Fat Controller arrives and asks Thomas to take the band. Thomas feels bad and tries to avoid Percy, but when he has to collect the band from Brendam he is found by Percy. Thomas, guilty, asks the Fat Controller to let Percy collect the band afterwards, and leaves to tell Percy of his plan. Percy and Thomas make up, and agree to never keep secrets from each other again.
