To answer all...Here's the thing, Sai realized that there's something about Sasuke. That said he wants to know but Juugo said, "Who knows." That means Sasuke is definitely planning. What's worse is that the editor note is saying that the dark clouds is getting close. That means something big is coming. We don't know but I got a bad feeling. What's worse is the next chapter is 8th chapter, which is known to be the twist or turning point. So, oh God, Sasuke, please don't turn heel.
Why it's bad?
