Freddy, here's what I suggest, because her audio is terrible and it needs to be addressed for the finished short: go back into the edit of this trailer and mute the music. Listen carefully to both actors. Close your eyes and listen. His audio is clear and up-front, with not too much of the "room" beneath his dialog. Hers sounds like she's in a bathroom... it's all "room" and no direct sound.
You say they were both wearing lavs, so where is that audio for her? It sounds like we're hearing her audio either from a camera mic or from the other lav, but it is clearly not from her lav. This may just be an oversight of the edit... her track was accidentally left out, unintentionally lowered or muted, whatever. It sounds bad, and if the audio from her lav indeed exists, it's an easy problem to fix.
It also sounds very much like the keys dropping on the table, and the purse dropping on the table, are production audio or even scratch (camera mic) audio. I'd replace those with SFX or Foley.
