Yours: Tokophobia - The fear of becoming pregnant, or of child birth.
You try not to show your fear to Jonathan, he is the Scarecrow, Master of Fear after all, but you know he'd never use it against you regardless. At least you hope. Due to your rough childhood, you developed a fear of pregnancy in a sense you believed that you'd become just like your mother and be a terrible parent. Jonathan didn't learn of this until he brought up the subject of wanting to have kids eventually and caused you to have a panic attack because of it. Rather than use this information against you, he became curious, wanting to learn how you developed it. It took a while, but eventually you told him about your family history. This took a lot of effort but he appreciated it because it showed that you trusted him. Now he works at trying to resolve your fear while making sure to respect you. Needless to say, you make sure he has protection before anything happens between you two. 😉
Jonathan's: A specific type of Thanatophobia - the fear of losing someone you love.
To learn the Master of Fear even has a fear is shocking to you, but once you find out about it, it almost becomes sweet. It took a lot for Jonathan to admit to you his fear, but when he did, he felt much better about himself. A lot of it came down to trust, and unfortunately you trusted him a lot more than he trusted you up until he admitted his fear of losing you. It didn't really change anything between you two, Fear didn't have the same implications to you as it did for him, as in you saw it as a natural occurrence not a weakness. It did explain why he is so clingy and very "in-your-face" sometimes, but now understanding why he acts that way you find it less annoying and more endearing though Jonathan insists that he'll get rid of the fear. He hasn't yet, and whether that he because he doesn't want to or something else, you'll never know.
