Cale thought about the question for a bit before raising his hand. "Well, without Ron and Hermione he wouldn't have been very successful at all when trying to find the Sorcerer's Stone, or the Chamber of Secrets...for all we know he might not have even survived his first Quidditch match, because wasn't it Hermione Granger who stopped that curse that was trying to buck him off his broom?" he wondered aloud. "Plus, he wouldn't have had anywhere to go during the holidays if Mrs. Weasley didn't invite him to her house, and although it's not essential to his survival or anything I think it made him feel a bit better knowing that there was a least one family that cared for him."
