Porthos' look of shock is completely expected when Aramis decides to blatantly rush forward into accusing Porthos of the truth, which he suspects is revenge for when Porthos had first brought the feline into their lives. He shakes his head, making sure that Aramis gets a full and clear look that he's going to pay in turn for such information.

Porthos settles on the chaise, his gaze fixed on Aramis with a bright grin and the fondness that always comes of watching little Athos seek out his affections in Aramis' arms. His heart warms at the sight, bursting over to have Athos so near. "There was a specific facial resemblance," Porthos finally concedes. "It was that or Bunny," he adds with a shrug.
