Mudstar's Links
He trusts Yewbranch the most out of anyone, but even that isn't much. After having lost two previous deputies, he's fearful of losing Yewbranch as well.
He takes it upon himself to take care of Mudstar because he knows he can't take care of himself. It's aggravating, but he honestly wouldn't know what to do without Mudstar.
He thinks Tanglepromise is a StarClan spirit.
She doesn't know much about her father besides his prowess in battle. She keeps tabs on him.
He is discomfited by the combination of Blossombird's confidence, clear intelligence, and casual disregard for others. He once considered appointing Blossombird deputy but was too paranoid to do so.
He used to idolize Mudstar like many others. He sought to learn everything about him, but the more he learned, the more obvious it became that Mudstar was just a normal cat. Now, his feelings toward Mudstar are extremely complex. He's working to get Mudstar deposed, ostensibly for the clan's and Mudstar's safety. After all, being leader is a dangerous job that normal cats can't handle.
He thought of Fleetbreeze as a kindred spirit and relied on them as his deputy. After their death, he blamed himself and immediately began preparing for war.
They didn't understand or care about Mudstar's issues, nor did they question why they of all cats were chosen as his deputy. They simply followed his orders dutifully.
