At first, Helex merely blinks, not quite comprehending the meaning of Tarn's gesture. It clicks a second or two later and he makes an O shape with his mouth, nodding. There are any number of empty buildings nearby that can offer decent cover; Helex chooses one with a door he doesn't have to manually enlarge so he can fit through and waves Tarn in ahead of himself.

"What're you doing here?" he asks once they're both indoors. Not that he isn't happy to see his commander. He's overjoyed, really, and his smaller hands twitch with the urge to grab Tarn by the shoulders and just hug him for a moment or two. Now might not be the time, though.
