Panel 2: Sigma says “Man, I really love the writing in this run!”. Rho looks at Sigma and says “Yeah!!”
Panel 3: A close-up of Rho’s face looking at the comic book. He says “And the art is great! I love the colors in…”
Panel 4: Rho looks at Sigma and says “Uhh…”
Panel 5: Rho (off panel) says “J–just trust me on this, okay?”. Sigma raises his hands in front of him and says “Oh, I do trust you!”
