Alderheart literally having the biggest heart ever by arranging Hawkwing and Violetshine to come and see Twigpaw's warriors ceremony:

"Hawkwing! Violetshine!" [Twigpaw] exclaimed. "I didn't expect to see you here."

"Alderheart arranged it," Hawkwing meowed.

"Yes, I talked Bramblestar into letting them come," Alderheart added, obviously pleased with himself. "I didn't want them to miss your warrior ceremony."
