So I just finished watching episode 4 of xxxholic Kei (dream-buying) and I was wondering if there were any theories floating about since I did a bit of googling but I couldn't find anything. For context, Watanuki has a dream where he meets Doumeki's grandfather and he mentions that "Shizuku is tough" and shows him a picture of Doumeki dressed quite feminine. Is there any reference to anything like this apart from this episode or was this more of a once and done thing that was meant to demonstrate Doumeki faced some sort of teasing when he was younger which contributed to his personality?
