i don't have a pretty side-by-side for the 4th episodes. it wasn't as neatly packaged and easily cap-able but there were definitely some intentional parallels:
- sam "coming out" about his hair color
- a strong focus on quinn and kurt
- kurt having a heart-to-heart with burt
- football player(s) joining glee club
- and even a little nod to the pregnancy drama started in 104:
rachel: hey, i have something i want to talk to you about.
kurt: please, not another pregnancy.
as for episode 5, besides the obviously parallel of mckinley doing a school play (with queer themes) i'm predicting the parallel will be a line reused, maybe by the same character or maybe a different one (sam maybe?):
just a guess!
