At first, Angelina hadn't planned on accepting. She hadn't bothered Oliver with this because he already had so much going on in his life. He was dealing with Percy and keeping their relationship up, and apparently guarding him instead of going for jogs. Ang's 'boyfriend' had up and disappeared, and she could definitely see the difference. Maybe the twins were just bad luck, maybe she should have listened to Katie and Alicia and stayed away.
Upon hearing the door, Angelina got up. She was dressed an Appleby t-shirt and pyjama pants. Ang had considered changing, but it was just Oliver. There wasn't anything she needed to do, so there was no reason for Angie to rush to her office. Opening the door, Angelina nodded at Oliver. "Hey Oli," she said in a rather emotionless tone.
Without waiting for him to come in, Ang turned and walked back towards her couch. She was just so fed up with everything right now that she was beginning to not care.
