Everything about this page made me grin like an idiot.
Everything.But I'll make a list of some things in particular:
-Waltrip did an excellent job on the costumes. I definitely raised an eyebrow at Helen's futuristic outfit from the last page, but these seem much more realistic and also like something that people at a high school reunion would wear. They fit their personalities, but show how they've aged as well.
-Speaking of showing age, I LOVE how Michelle is done here. She's obviously still not the sharpest crayon in the academic drawer ("nationlist or just, y'know, ist"), but she's found her place in life doing something that she loves. I think her use of the word "nuance" shows that growth. But I do like how it's combined with a crush on Marshall, showing that some things will never change.

-Since we're unlikely to see them interact in the strip, I doubt I'll subscribe to "Marshelle." I do love seeing Marshall as a pre-med volunteer though. It was a great way to work him into the strip without having him just show up for no reason. Plus, I was always a fan of Marshall. I'm glad he turned out alright after all.
-Katy-anne's child(ren) really just speaks for itself. No to mention, she just looks so
content with her life.
-And lastly, those weird sexy tiptoe legs sprouting from Katy-anne's word balloon in the lower left panel. Lawl!
