I found a new ship

Was this cat trying to annoy him on purpose? Fireheart was struggling to hold back a sharp reply when Mousefur trotted up behind him.
   “Hello, Leopardfur,” she greeted the RiverClan deputy. “Stonefur tells me there are new kits in your camp, besides Graystripe’s.”
   “Yes, there are,” Leopardfur meowed. “StarClan has blessed our nursery this greenleaf.”
   “He also said Mistyfoot’s kits are about to begin their training,” meowed Mousefur. “You know, the ones Fireheart saved from the floods,” she added, her eyes sparkling with mischief. Fireheart noticed Leopardfur stiffen, but his mind was on Mistyfoot and her brother, Stonefur. He glanced around the clearing and saw Bluestar sitting alone beneath the Great Rock. Did she know her son was here? Had she heard that Mistyfoot’s kits were ready for their apprenticeship? When he turned his gaze back to Leopardfur and Mousefur, the RiverClan deputy was stalking away.
   Mousefur shot a look of sympathy at Fireheart. “Don’t worry. You’ll find her less intimidating when you get used to her. The rest of RiverClan seems happy to see us. They would not have survived the floods so well without the help of ThunderClan, and we did let them have Silverstream’s kits without a fight.” —Into the Wild
