You were in the lab with Barnaby working on some new colours, you needed to grab something and you told him you'll be right back.

Walden: huffs assistant...this is my father...Wallace darling

Wallace: assistant? Seriously? Your forcing them to do what you want? Huffs always knew you were a lazy child...
