Sigma has no time for your nonsense.
Panel 1: A food court stand for pasta. Sigma is standing in front of the counter. He says “Excuse me, do you have a Braille menu?”
Panel 2: The cashier (off panel) says “Braille? Is that the one with the dots…”, to which Sigma enthusiastically replies “Yes!”
Panel 3: The cashier (off panel) continues: “…and the dashes?”. Sigma looks confused. He says “What? no, that’s—that’s Morse?”
Panel 4: The cashier (off panel) starts reading the menu in Morse, shown as a speech bubble full of dots and dashes to represent the sounds. Sigma turns away from the counter with an expression that’s a mix of annoyance and disbelief. He says “I–I have to go”.
Panel 5: The food court. There are various people shown eating in the background. Xi is walking towards Sigma’s table, she’s carrying a tray with a burger and a soda on it. Sigma is sitting down eating sushi. Xi looks at him in surprise and says “Oh? I thought you were going to get pasta…”. Sigma calmly replies “I changed my mind”
