Panel 2: Sigma’s apartment. Xi and Sigma are on the couch. Xi hugs and tickles Sigma from behind and says “…to protect this precious cinnamon roll!!”. Sigma, laughing, says “Y–you don’t need to do that!!”
Panel 3: Xi lets go of Sigma and says “Are you kidding? it is my duty to—“. Sigma smiles calmly and says “Protect all the citizens of Omni, yes.”
Panel 4: A close-up of Sigma, touching his chin, thinking. Xi (off panel) says “And you are a citizen, yes?”. Sigma says “That’s true…”
Panel 5: Xi hugs Sigma again with a smug smile and says “Then my oath still stands.”
