Both on the Case

In "Sweet Dreams," from "Lockwood & Co." after George reveals a key piece of information, Anthony Lockwood states that Lockwood & Co. should be the ones to investigate the case. This doesn't sit well with Kipps's team of the Fittes Agency and the two groups immediately set to arguing until Inspector Montagu Barns cuts through their babble with a loud "SHUT UP!" then tells them he's putting them *both* on the case.
