Lord Bertram is mentioned at the start of episode 22 around 2m40s. Will mentions having an appointment with him at 3 o'clock the next day. Will asks for the materials about the Seacroft Company he is pitching.

Later that is shown, but Bert rejects the offer, calling it 'dodgy', based on learning of Will's reputation regarding keeping his promises.

He is voiced by Tomomichi Nishimura.
