I love that it looks like some sort of weird religious ritual, but nope, he and Sophie are just catching ladybugs in the jar she's holding. The circle on the window? That's a ladybug trap of Izzy's own invention.
Shortly after this, they set their trapped ladybugs free. Ladybugs, whom I'm sure returned to our sunroom shortly thereafter, only to be wickedly sucked up into a sure death by Chris's Dyson.
