Felix's friends really knew how to throw him under the bus. When Rachel asked Artie if he was single, they all looked at her in shock because it seemed like she was asking him out but then she clarified that her best friend was interested.
Artie was hesitant until Toby volunteered for him to double with them. Why did he have to drag Felix into it when he knew that he wasn't interested in Rachel?
She was just a kid! Albeit a very professional and talented one.
He already knew about how many instruments she played but his friends were shocked. Her major and why she picked it were news to him though. That was a very sentimental thing to do but it made sense considering how much she had missed her parents and wanted to go home to them. It must have been hard finding out one of them was already gone.
