Maybe Echo was the better person to talk about this with anyway; he was the one always skulking around the city like he was looking for trouble. It definitely shouldn't have been Cal's problem, Tony realized, biting his lip with a nod of understanding, and he tried not to look too sheepish as he abruptly turned his attention back to the bench and busily dumped a container of scrap he pulled carelessly out from below it. Spreading the pieces that looked like they had come variably from a kitchen drawer to an industrial vacuum, Tony offered, "Come on, let's make a relay launcher." They might not actually need it, if the problem was only a power one, but they could definitely use a...launcher, and maybe Cal would show Tony how to use his tool as they worked.
