I can understand Asuna's mom's actions. It's obviously not a warm family. The maid (they even have one!) looked quite nervous as well. The mom likely has adapted to such an environment and hasn't watched enough dorama to know any better. Furthermore, since she herself wasn't born into a rich family, according to Asuna, marrying into one must have been like a dream come true, until the reality struck. But she could hardly admit that reality, lest she has nothing left. So, that's her concept of a successful marriage: Two people from the same social class marrying each other to keep up their wealth and status and naturally to propagate, having the offspring play the same game. Everything else is inconsequential, happiness included. Naturally she would wish success as great to her own daughter. All in all, I doubt dinner is the only time when she's drinking wine...

Asuna obviously never shared the same values, as she escaped the coldness (15C room temperature, damn) to the virtual world.

Do they have some steam punk swords or where on Earth did all that steam appear from during the fight? It looked ridiculous.
