The sound Tarn makes is painful to hear; Helex can't imagine what it's like feeling that sound in his vocaliser and he grimaces at the thought. Surely they can get that fixed, he thinks.

But he doesn't get much time to think about it before Tarn is settling down and writing in the dirt instead of trying to sort out speech. Probably for the best. Helex watches the words form and mouths along as he reads, half-mumbling, half-breathing them out of habit. When he finally processes them, he frowns.

"Nothing to apologise for," he says quickly, waving off the very notion with one large hand. "Least not to me." His tone shifts, turning curious, and he adds, "Miscalculating isn't like you. What'd I miss?"

He had to have missed something. He's loyal to Tarn and Tarn in turn relies on him often, but that doesn't mean Tarn tells him everything.
