I'm glad to be wrong; it's Mike and Lawrence talking about the snow.
Panel 1: Mike and Lawrence are outside as it snows; the future Delicate Genius says "Look up into the sky, Lawrence...an' don't look at anything else."
Panel 2: He continues by saying "When the snow falls towards you, it feels like you're flying upwards into the sky, doesn't it?" Lawrence says "Yeah..."
Panel 3: "...except that my feet are touching the ground." Mike tells him to forget his feet which makes Lawrence ask how he can do that.
Panel 4: Mike says "Just stand here long enough an' you won't be able to feel them."
Summary: This is a harmless enough bit of fluff; granted, I'd expect a conversation like this from ten-year olds but we can't have everything.
ETA: Lynn has just divulged her holiday schedule.
