"I hope you know that I am absolutely going to take every single advantage of that 'call me out in private' thing," he added, as a side note. He'd just shamed himself - acting like a complete (playful) douchebag was the only way he could think of to protect his masculinity. It was all in good fun, and he hoped Lachesis understood that. After all, he was immensely, overwhelmingly grateful for the white-pelted man.
On a slightly more serious note, the mocha wolf perked his ears, recalling something that he'd spoken about with Lach in their last conversation. "Oh! There's also something really important that I've been meaning to talk to you about." Perhaps if he continued talking and talking like a moron, his alpha would forget that he'd just cried like a heartbroken pup. "I've decided that I want to become a Guardian." The sentence was spoken with surety and pride - his chest even puffed up a little bit.
