Josh was so caught up in his own irritation and exhaustion that all he could do was take it all personally. The silence definitely wasn't good and he just thought it was all about Aidan acting so weird towards him. As if he was the one to be worried about when his vampire friend had been buried alive for A LONG TIME. Josh wanted to roll his eyes right out of his head.
That is until Aidan asked about where he was sleeping. That just pissed him off. He tilted his head with a hollow shell of a smile plastered on it, letting out a fake laugh "What? What is this...some kind of interrogation? Yeah I worked late last night, so what!" he was shuffling his weight the way he did when he knew he was in trouble, laughing a little too much and trying hard to keep that smile on his face when he wasn't feeling it at all.
