She watches it become a grief seed, then turn back... into a soul gem.

It's such an utter surprise that Homura finds herself hoisting herself up without even realizing it, walking closer and then sliding back down to her knees. She is completely bewildered for a moment, just looking over the soul gem. She glances to Mami's own face and then back down.

The shock of this is little in comparison to reliving one of the worst moments in her life, however-- and so, Homura looks to Mami as the girl she was so many timelines ago. She looks to her as someone who should be steadying but is not at all. She does not look to her with fear or disdain or hate, as she might have otherwise.

She sees her through a pair of red glasses.

And though Mami may not see Homura the same way as she sees her, that does not matter to her right now. Her friend... that's what Mami is. And her friend, her mentor and her adviser, is hurting. Is scared. Homura might arrive at anger eventually, but right now... in this very moment, that does not matter to her. She acts on instinct rather than logic.

Gently, as though she may break-- Homura reaches out and touches Mami's shoulders. She draws her into a hug.
