During the reconstruction, you had gotten to know the Royal Guards a bit better, since you saw them all the time when they were on duty, and true to the magic, you weren't able to tell them apart. Which, of course, earned you the laughter of various mares when they visited you during their off-time and had you play the guessing game over who you met with clues and teasing. It was an excellent conversation starter, but the mares always went off on their own tangents; you could tell they'd been starved for somepony to talk to, especially since they were on the castle grounds all the time.
