I haven't noticed any voice confusion, but if you're worried about it, maybe it would help if you kept in mind that Gibson's snark isn't born out of any issues; he just walked out of the Sea of Simulation that way. Sam's is armor. Gibson will take any opening offered, while Sam will use the sarcasm as a defense mechanism when someone gets too close to a painful topic.

Regardless, I enjoy our threads immensely, and consequently there need to be more of them. ♥
