I kept meaning to ask this throughout the whole show and I kept forgetting, so now, before it's too late:
For those of you who also saw "Wedding" (Wedded Bliss), remember the skinny, odd-looking brother behind the bar? The one who said "I like Princess Pink" toward the end of the show? Wasn't he also one of the doctors in Dr. Park's cadre? I don't know the character's name, but he had a few lines here and there.
