I was thinking, what if Kirito gave Asuna the cambear? He doesn't know that it's a spy bear, the great thing is that from the other side Suguha could clearly see what's going on, it depends where would she have put the bear spy, if in his room, then Suguha could see all (the evidence)
*Suguha turns on the PC*
Suguha: wait a minute, this doesn't look like Kirito's room, wait, who are these two? oh my god, I can't believe it, I knew something was wrong, that that bitch Asuna was cheating on Kirito, now I have clear evidence
and here the question arises, if this scene would have happened, what would Suguha have said to Kirito?
