Mikasa, who was prepared to die alongside Eren, comes to him and thanks him for being with her eventually, for the will to survive, and, of course, for the scraf. He berates himself for being weak and unable to change anything after all. For the non-chinese readers: What happened was that upon seeing the death of Hannes, Eren realised he is once again powerless to prevent another death of a closed one from the same Titan who killed his Mother. Eren can't transform cause most of his power already went to his regeneration, but you can see some of his titan power manifested with steams coming out of his hand while he controls the titans. And someone here posted that the titans with skin and have elf ears (Eren, Monkey Type and Ymir) all may have this power.

Also, why didn't Eren just transform?The titans control power has been demonstrated to an extent by Annie and Monkey Type earlier, so it's not out of nowhere.
