As soon as you start to ask, Tamru pushes in closer, interrupting. "And on top of everything, there's a new human? How come nobody came to get me? And, of course, nobody told me about Cinza or the air ballasts either. I had to just overhear gossip from others. Nobody even came looking for me." You can't believe just how poorly everyone else has treated him. Certainly, he has every right to be angry.
He retreats back into a corner, where it's easy for him to brace himself and stay steady while talking to you. Back when you two were together, that's the place he used to settle all the time.
