Snape was afraid.

In fact, he had had many things to be afraid of in these past months. He was worried about Harry if the boy lost his appetite and showed symptoms of catching cold or fever. He was anxious about Harry’s grades and how his son did at school. He guessed it’s normal for a parent to feel that way. But he couldn’t just erase the feelings.

Snape reminisced how he had been months before Harry came. Snape had had very little to concern. His job hadn’t been too demanding at that time. He had had much free time for himself, though the majority of it he had spent to brew potions.

But he didn’t regret all the mixed feelings he had now. Snape was grateful he had a son. Harry connected him to many people he had never thought he could be friends with. Snape still chose to be a concerned father rather than to be a lone and free man. Fatherhood had changed him. Some people pointed it out to him, and Snape agreed.

But Harry wasn’t the only one who made him feel anxious.

Snape was afraid he started to fall for Sirius. At the beginning of their relationship, Snape hadn’t given much thought about it. And then Sirius showed his possessiveness. The man made it clear to everyone that Snape was already taken. Snape was annoyed, of course, especially when people inquired how they became couple. He was vexed when asked if Amortentia played huge part in it.

But he was only human. He couldn’t be immune for too long to Sirius’s constant affection, attention, possessiveness and presence. If usually it’s Sirius who showed jealousy –even towards Lupin- now Snape started to know the feeling.

The Potions Master was jealous when Sirius smiled to the beautiful young women in the bookshop. His temper hit the roof when the man in the robes shop touched Sirius’s arm to get his attention. Snape felt something ugly churning in his stomach when Sirius was friendly to people, in general.

It’s not good. Snape was really afraid of losing him.
