Claire and Chris weren't aware they had another sibling, let alone a little sister. They only found out right after Raccoon City, because they were doing DNA tests on survivors.
And technically, you were a half sibling on their Mom's side. Only being 2 years younger than Claire, it pretty much made sense why it was hidden. Their Mom had some kind of affair. And neither of them were old enough to remember her being pregnant.
But they knew now. And you did too. They didn't know what to do. You were 17, you were old enough to reach out if you wanted to. They didn't want to force it. But they also really wanted to meet you, especially after the trauma of Raccoon City.
They eventually reached out themselves, and you agreed to meet up. You were meeting up with Claire first. And Claire? She was a bit worried. She didn't know what to expect.
Now she sat in a coffee shop, sipping some overly sweet latte while waiting for you.
