"Sometimes she got this look where she pinched her brows together and her bit her lower lip." why does it use "where" here ?

Hello Sharon

"Where" is sometimes used to introduce a clause that gives further information about something in a previous clause. It has a number of senses, in this usage: "in which case", "in which condition", "in which circumstances", etc.

You can think of it as a metaphor. Here's the literal use of "where":

1. I went to an island where there were no people, only birds.

And here's the metaphorical:

2. Sometimes she got this look where she pinched her brows together...

Just as "where" in #1 refers back to "island", so "where" in #2 refers back to "look".
