Yes! That was when I did, too. I was all, "!! Parker IS bisexual!" I can imagine someone asking, and Parker saying, totally casual and deadpan, "She smells pretty." I think Parker probably fell for Maggie while they were in the van, listening to her tear down Nate's ego (which, honestly, is when I fell for her).
I shipped Parker/Maggie the instant Parker did that awesomely deadpan crazy hair sniff. ♥
