I predict that Wren and Cath will become closer as time goes on. When Wren got hurt, even though her and Cath were in a fight, Cath still went to the hospital to make sure that she was okay. Wren and Cath have also talked a lot more after that moment and became closer. These examples show that they care a lot more about each other then they did. I know this because when people help each other, it usually means that they care for each other
I chose to use this video because it shows two sisters hugging which usually means that they care for each other like Cath and Wren do.
