There's another episode where a Klingon headbutts Data and almost KOs himself. Data didn't budge so much as a millimeter from it. (Data said the duranium could survive extreme stress) So I figured the metal spike should not have been able to penetrate him. At least not by an average humanoid.
Also, I got another episode with "maximum warp." They seem to be throwing it out a little more frequently now. I've heard it more in Season 7 alone than in the first 6 seasons combined.
Also, "Lower Decks" was a great episode. The blonde girl (Worf's protege - Bajoran girl) looked like she had the most amazing ass. Damn.
