Tim and Jenn share a panel. They both wear their adventuring garb. Tim is on the left, Jenn is on the right.

Tim : I learned a new spell. Without making any sounds or gestures, I can create an effect that you can't possibly detect.
Jenn : I didn't fall off the turnip wagon yesterday, you know. That sounds like you're not doing anything at all.

Tim points an accusatory finger at Jenn. She looks at him with a flat expression.

Tim : Oh yeah? Since when are you an expert in the arcane arts? Let's face it. I have so much magic kung fu that I can do all kinds of awesome things behind the scenes and you'd never know it. In fact, the only way you'd find out would be if I told you.

Close up of Tim. He clenches his fists in front of him and his body radiates with eldritch power.

Tim : Therefore, behold the true extent of my power! My magic is so awesome that I can do things you can never possibly understand! And because you don't understand it, you can't even know if I actually did anything at all! Bwhahahaahaha! *** New Panel *** Tim and his boss share a panel. The boss is behind his desk, Tim on the other side. The boss looks at a big stack of papers on his desk, between him and Tim.
Boss : That looks complicated. Did you do it all?
Tim : Oh yeah. It was awesome.
Boss : Good work, then.
