The comment about dirt made Glitch pause, it was very likely he might have had dirt in his head and didn't know it. "No, I did not. But who would when you're memory is faulty. Memory is faulty. Memory is faulty. Memory is faulty." he repeated the same speech pattern and mannerisms over and over quite a few times as he became stuck in a glitch loop.
