Honestly I thought it was weird that she asked him to sit with them when they were on a date... kinda insensitive... and I think Alphonse was more protective over her and he was probably just annoyed that he was talking to her :/ duchess needs to keep alphonses feelings in mind before she does stuff like that imo smh imagine if your bf/gf just invited someone to hang out on your date and then they only talk to them
