Asuna is going to show up and Kirito is going to be like, "You're not Eugeo." While desperately clinging to Eugeo's sword.
Then, through some miracle, Asuna will wake him up. Reacting to the dormant anger from the loss of his boyfriend, Kirito will dual-wield and solo the entire demon army. Meanwhile Alice will be like, "Yo, who is this red-haired bitch?" And, Asuna and Alice will duel to the death while Kirito mourns Eugeo in the corner, alone.
The rest of the Kirito harem will show up and be like, "Kirito, you have forgotten who you are, and thus you have forgotten us." Then Kirito will be like, "The only thing I remember is the taste of Eugeo's lips."
Meanwhile, the main "villain" of this arc will be like, "I'm here too guys." And because he's so inconsequential Klein will one-hit him so we can focus on the sexual tension between the Kirito-Eugeo-Asuna triangle for the remainder of the season.
