I know, I didn't post a chapter yesterday.. again. I'm sorry. Just to warn you I'll be probably gone for one week, so I won't be able to post a chapter.

The sisters talked until 4 o'clock. When they finally fell asleep, the sun was starting to wake up.

At 9 am, Natasha woke up. She left the room to let Tanya sleeps. She found Steve eating Pop-tarts on the couch.

''Good morning'' he said.

''Good morning to you too'' Natasha answered. ''Where's Clint?''

''At his apartment. He left after the movie. You know, I can keep an eye on your sister if you want. I live here, you know.''

''Of course I know, but I already asked Clint, and he already accepted. But if you want to help him, go ahead.''

He nodded.

Ten minutes later, Tanya woke up.

''Good morning, baby sister'' said Natasha once Tanya was in the living room.

'' 'morning'' Tanya answered.

''If you want to eat, search in the fridge.''

''Thanks.''

''What do you want to do today?'' asked Natasha while her sister was searching for something to eat in the fridge.

''I think we didn't shop enough yesterday.'' answered Tanya.

''So, you want to go shopping?''

Tanya nodded.

'' I think it's going to rain, so this is a good idea.'' said Natasha.

''But only together this time.'' rapidly said Tanya.

''As you wish.''

The sisters shopped all day. It was raining cats and dogs, and at the end of the day, they could hear thunder.

They went back at Stark tower at 8pm. They listen a movie with Steve. At the half of it, lightnings began to light up the sky. Steve saw that every time they hear thunder, Tanya was closing her eyes. She was looking scared. She finally gave up and went to bed.

''I think our friend Thor scares Tanya'' said Steve.

''She has always been scares by thunder'' answered Natasha. '' I'll go see if she's okay.''

Natasha went to see her sister. Tanya was completely hiding under the blankets.

''It's only a little storm.'' said Natasha.

''A scary little storm.'' answered Tanya.

Natasha started laughing. She jumped on the bed and began tickling her sister.

''Stop it!'' screamed Tanya.

Tanya began to push her sister and unintentionally, she made her fall of the bed.

''Oh my God'' yelled Tanya while removing the blanket that was hiding her head. ''I'm so sorry!Are you okay?''

The only answer she got was the laugh of Natasha. Then, she started laughing too.

''Don't scare me like this anymore'' said Tanya.

''Don't worry, I'm okay'' said Natasha.

She got on the bed again, and sat down.

''Promise me you're going to come back from your mission.'' said Tanya.

''Why?'' asked Natasha. '' I can't promise you something that I'm not sure of.''

Tanya looked away.

''Don't say that'' Tanya said.

''Okay... I swear to you I'm going to come back.'' said Natasha.

''Promised?''

''Promised''
