Yamato is starting to realise that he hasn't actually eaten yet. Not for lack of availability of food, and he's pretty sure he could ask Barry to go and get him a burger, but he's been absorbed in work -- recalibrating the satellite is a slow, careful process, not least because the data he got from his scan is, while useful, not extensive.

Still, Barry might occasionally catch Yamato's attention drifting over to his chicken nuggets, and the brief flickers of a facial expression that would not be altogether out of place on a puppy watching someone eat.

At the moment, the computer is building a predictive model (the fourth one, after Yamato decided that the first three weren't fit for purpose and set about changing the parameters) for dealing with shifts in the signal, which means that Yamato just has to wait.
