There are two kinds of torture in a place like Wonderland. One is Taako's. One is Lup's.
She could hear everything, and it was agony. She knew before Taako did that it was wrong, that there were a couple of immensely powerful liches out there who were manipulating reality based on some incredibly powerful dark magic. And she was horrified at the thought of what they would do to her brother and her friends. But her horror was nothing to what it became as she watched it happen.
As they sacrificed more and more to the liches's insatiable hunger, she began to pace, to shout, to claw at the curtains that hemmed her in, desperate for a way out, but of course to no avail. She was absolutely frantic. Taako was losing more and more of himself. She could hear his exhaustion in his every word; she could see him giving up.
She tried to gather more power to herself, but it was harder like this, when she couldn't concentrate. And it wasn't just Taako, although he was definitely the worst of them. Merle and Magnus were in dire straits too, and she could see Merle working harder and harder to maintain his composure while spell after spell flickered away, all but powerless. Magnus… bless him, he was doing everything he could to stay positive, but what was sustaining him? And could it last?
It was the Boss Rush arena that gave her the first flicker of hope - when the staff consumed Jenkins's wand. Lup did not hesitate. She channeled all that power back to Taako with so much force that when he stood up a bit straighter she wasn't sure if it was her that did it. But the tiny smile that flickered at the corner of his lips was all him, and she was thrilled to see it.
And that fucking T-rex was the shit. Lup was screaming and cheering and begging all the gods that it would work. And it DID.
"That's my BOY! That's my brother! YES!"
