new things I've noticed

By making Sam a forever-baby-sitter, they give her that in common with Laurie Strode. Really one aspect missing from Sidney, that they try to redeem by making her a mom and passing the torch to Sam.

Also, the twins now have in common that they've each lost a girlfriend with a questionable dye-job to a Ghost Face killing spree

Gale's scene is notable solely for being her first direct call with Ghost Face where she's the target. However, let's not forget. She was attacked by Ghost Face in costume in 3 and 4 as well. In 1, 2, and 5, the masks had come off before her arrival. And let's not forget Ghost Face also taunted her over the phone in 2, along with Dewey, Joel, and Randy, who ultimately died at the end of that call.
