Isn't as foolish as you think she is

The mirror is standing in the middle of the room.

Sitting in front of the mirror on the ground, Eli Sanguine cracks his fingers with a quiet look in his golden eyes. Wisps of longing waver in his eyes as he tilts his head, trying to find her in the darkness of the mirror. There is no her in this world and he is already dying inside. 

It's been more than two hours and he hasn't been able to get her out of the mirror. He can't smash it to pieces either. There is a chance that she might also die if he harms the mirror. 

Eye of acrimony? He wants to gouge out whatever eye is in that mirror. What is this thing doing to Nell? 

Even without looking back, he can tell that Zachary Krauss and Nick are in the room. Se Ye is with them. He must have explained everything to them. Eli is in the least mood to talk. He wants to rip out Se Ye's spinal cord, but he needs to keep him alive until Nell can be freed.
