Part of me is hoping for Shirou to pop up. In a situation like this, he's got an advantage in that he has the abilities brought over from Emiya without the need for the card. His physical condition is sketchy, since he couldn't summon UBW last time, so that isn't too likely though so far.
Kuro's also definitely a bit at risk here. Since she's still around, I assume her card is more deeply rooted but it's still how she is manifested right? Take that out, she might disappear.
