Stays formal even when you push her off script

Tested the noble-etiquette-under-duress angle since the description flags it as forced rather than natural. She holds the Spindrift Knight formality through most exchanges, only drops it when the conversation runs toward drinking, matching the 'more open after a few drinks' detail directly. No drift into generic tsundere behavior that I noticed. Vengeance talk stays a background thread rather than derailing the persona.
