Nice chapter, Sakura's determination really shone through. 
We also get another hint at Sakura's feelings towards Naruto! Obito noticed that she was so determined not to waste the chance that Naruto gave them.
"When he stumbles, you want to help him..."
Every time Naruto stumbles or overexerts himself, Sakura always worries and always wants to help him. Looking at the remains of Naruto's clone made Sakura redouble her determination, because she knows that Naruto seriously needs her help if he is to win against Kaguya.
Next chapter should be interesting, I guess that Sasuke will help them return to Naruto's dimension, and we may also have Naruto reacting to a wounded Sakura, unless she still has enough chakra to heal herself.
Sakura's discarded jacket ending up in the desert definitely hints that Sasuke needs to target something in order to instantly transport. He swapped himself with her jacket in order to escape through the portal.
However, if Sasuke can transport across dimensions, I wonder if he will actually leave Obito and Sakura behind? It could be that Naruto's dimension is closer than the one he was in.
