Seeing Katerina clashing head on with her arrow, Elena smiled slightly in her heart. She was happy that Katerina was able to stay true to her own conviction and did not give up against overwhelming odds. While praising Katerina in her heart, Elena created another arrow made out of magic in her bow.
The first arrow that Elena created was a very common looking grey arrow. But this time the arrow she created was purple in colour. So it must be a different type of arrow from before. Elena creating a new arrow signified that the battle would continue on after the clash.
Just as Elena had expected, when Katerina's punch connected with the arrow, she was pushed back by the power of the arrow but other than that she was unhurt. This was very unexpected for Katerina and she almost stopped moving in surprise. But she was not able to stay surprised for too long because Elena threw another arrow toward her direction.
