Has Tim called Lucy by her name ever?

I’m on season 2 episode 15 so please no spoilers. I just noticed that Tim always calls Lucy “Chen” or “boot”. It got me thinking and I can’t remember a time where he calls her by her name (I mean when talking to her not to other people, because he does say Lucy when he’s on the date with Rachel). If any of you guys remember, has he called her Lucy ever up until this point. Maybe he has and I’m just making a big deal out of nothing. Again please NO spoilers.
