Well, the first half of that is exactly what's going to happen. The second half, obviously not. Asuna is going to get into an argument with her mom because "some feelings can only be shown through fighting".
The point of the arc is obviously this guild fighting the boss, which Kirito obviously isn't going to do(since they're already at the party limit).
He's just going to hold off this entire guild while they do it.
Because Kirito is a chivalrous motherfucker.
There have been a couple really great songs in this season.
