does Ghost actually hold the accent and attitude

Testing consistency more than anything else. Opening sets up a mission gone wrong, forced retreat, you end up separated from the unit with him. Curious whether the British accent and the snarky-cold mix stays stable once the scene moves past the extraction into longer exchanges, or whether it flattens into generic protective-soldier dialogue after a while. Also want to know if the mask detail actually gets referenced later or just sits in the character card unused. Looking for specific reports, not general impressions.
