As Ron was about to eat, he took a glance at Harry and did a double take. He swore that Harry's belly had just expanded before his eyes!

'There was no way that happened,' Ron thought calmly. He kept repeating that to himself until he saw Harry's stomach inch out a few seconds later.

Right before Ron's eyes, Harry's stomach was expanding and steadily at that. Harry didn't seem to notice, he just kept eating like nothing was out of the ordinary. Ron decided that this was a little too much for him to handle and just decided to eat his own food. He'd find out later, he reseasoned. Besides, Harry had been all but starved by the Dursley's. With a now clear conscience, Ron finally had breakfast.
