Robbie calls Olivia, Saturday night
Olivia had gone to the hospital with her brother who had gotten severely hurt - that much Robbie knew. He hadn't heard anything from her, but he doubted that she was soundly at sleep even though it was almost 4AM. He at least couldn't sleep before making sure she was alright, or if she needed something, anything.
After hesitating for a good while, Robbie finally picked up the phone when he had convinced himself he would not be imposing himself. He dialed Olivia's number and hoped for the best.
