Apparently she was working in the same company as Frances. When Frances went to stay with them for dinner I first thought that Rachel was Sophie, because they looked alike and I thought Sophie had just taken her glasses off....... AND Frances said that thing "ahoy sexy" or something to her when they met.
So what exactly was Rachel to Frances?
Yep, they worked together. In the beginning of the movie, they are seen talking before their dance rehearsal.
shareSophie gave Lev the cell phone number of Frances. Lev immediately sent Frances a text message. The 'Ahoy Sexy' was *I think* a salutation in the text sent from Lev to Frances. She reads it on her phone in the presence of Sophie.
Rachel didn't look like Sophie to me.....
Yes, Rachel was a company member in the dance company where Frances apprenticed. There was a brief scene with them together warming up, etc.
