Love is for children

When Natasha notices that she is starting to develop feelings for Wanda Maximoff, she doesn't want to admit it to herself. "Love is for children", this is what she was taught over and over again. She makes the decision that this is probably just sexual tension and if she has a good time with Wanda, it will all be out of her system. When she's on the next mission together with the Scarlet Witch and she sees Wanda is in danger, she risks her own safety to make sure that the witch is safe. This results in Natasha getting shot and ending up in the hospital wing, and more importanyly: being forced to take a closer look at the emotions she is feeling.
