Actually, it's MikeClone having to take what he dished out last week.
Panel 1: We start out with AnnePrime telling Christoclone to share his raisins with MikeClone. After he refuses, she reminds him not to be selfish.
Panel 2: The blond kid gives MikeClone the stinkeye.
Panel 3: He then spits some of his raisins into his palm.
Panel 4: And then offers his hostess's son the mucus and germ-covered treats.
Panel 5: He next tells his mother, who watched the stomach-turning transaction, that MikeClone didn't want any.
Summary: If it were any other child, I'd feel sorry for him. Also, I'd expect that the tow-headed little boy would next express genuine confusion that his mother meant to share the raisins that were left in the box.
ETA: Check out the new banner on the Foob page. It's about time she put MikeClone on the page again.
