When Frank is in the hospital bed and says, "No kissing!" he looks straight ahead. In the next shot, his head is turned toward Marie.
After Robert and Marie leave the hospital room, Ray walks to the door to close it. As he is closing the door, you can still see Robert standing in the distance but Marie is now no where to be seen.
When Debra is in the kitchen and learns Ray has told his buddies about their accident there is a dimple/indentation in her sweater. Later, actually mid conversation, and for the rest of the episode, it's gone.
