Rick's sister rolled Jim out into the hallway and into her room. But Jim's spherical body was too big and weighed quite a bit more than Rebecca expected. So when he bumped into her bedroom door frame, he obviously made a grunt from the pain. This got Rebecca's attention. She looked down at the strange ball of putty, wondering if she just imagined the grunting noise. A lump of putty wasn't alive, afterall.
At the same time, Jim became nervous. He let Rebecca know that he wasn't just a ball of clay. But he decided to wait to see how she reacted before making any moves (at least any moves that he was able to make, in his current situation).
"Is anyone there?" Rebecca finally asked, after a few seconds.
