To chip away at Yugi mentally, of course. A cheap but dirty tactic. We all have our share of negativity and secrets so it's common for us to keep it buried and pray no one finds them.

[Saori walked over to Yugi and got down, gently putting her hands on her shoulder.]

Yugi, hear me out. Your friends did what they had to do because they sincerely care for you. The same goes if they ever got angry with you. I think it's safe to say they know you would've done the same if the situation was reversed. Also remember that strength comes in many forms. If this is truly your shadow, remember it's only one part of you and not all of it. Don't let the despair consume you.
