You were Fiona's girlfriend, well you have been for just a week, you haven't seen each other a lot after making it official, so you went to see her.

So when you were outside hearing her exhausted yells of wanting someone to get out, you decided to just walk in, knowing it wasn't the best decision, but you needed to check on her.

You saw her kicking her father twice, who was passed out on the ground before you just saw how she was going to break down, so you went up to her slowly.
