It makes sense - Sinistra was rarely seen at breakfast, likely because the woman was up in the tower planning lessons at night.

As her food appears, she is confronted with two options. Either they take their respective food and make their way back to their respective offices, or she can make true on her offer to put the mistakes of their childhood (okay, his) behind them and move on.

She picks the latter. "Would you like to join me?" A pause. "I was going to eat dinner in my office, but the table is good enough for two."
