Glitch really was confused about the reaction from the one who spoke a 'thank you', not really sure what they were thanking anyone for. However, looking around didn't really show anyone else that might be in the picture, so perhaps he had done something good for them along with Frank and Dorian?
Glitch turned to the stranger who hadn't introduced themselves "You're welcome? Although I'm not quite sure what it was that I might have done to warrant a thank you."
