"Everything is going according to plan."

Dr. Pepper often looks calm and collected, and like he knows what he's doing. He's very charismatic and has a way of convincing people that what he says is true, even if it's complete bullshit.

He is pretty narcissistic and acts like he's the coolest and the best guy out there, which he probably actually believes. He often compliments himself and flaunts his achievements to others. He expects people to look up to him and listen to him, and oftentimes ends up telling those around him what to do, even if they didn't need or ask for his advice.

He's actually pretty clumsy and often embarasses himself, turning around and saying that he meant to do that in mock confidence, no matter how much shame he is really feeling. He's very quick to get defensive and aggressive if someone points out these incidents to him. Sometimes his clumsiness has gotten him into actual trouble before, though he can't seem to be able to avoid having these little accidents quite frequently.

Probably bought his medical license online.

Grew up in a rich family, and inhereted a lot of their money. He invested it into his own business and selling his ideas, and has a steady income of his own now.
