While, as I have said before, I would like to see Suguha go down the Yandere Bro-con route. I am struggling to imagine what her future developments would be like without Hebishima, because I can't image Fujino solely having her scenes revolve around Kirito being taken advantaged of or unknowingly interacting with her through the game as Leafa. The game doesn't look to be anywhere near the ending, even if we might be more than halfway there, but someone needs to play the "bull" role for Suguha (and Sion as well), so even if Fujino graces us with a Kirito(asleep) x Suguha scene in the next update, and she doesn't fall back to her netorared heroine ways, I can’t see her not sleeping with Hebishima afterwards for whatever reason, be that money, fun, drugs, or blackmail.
Anyways, we only need to wait one more week to know for sure as next update will probably tell us what will happen with her character.
