I was disappointed we didn't have Three, Four AND Ten in the flashback sequence! (I R GREEEEDEEE!!)

Plus, the "more than just romance" thing pleased me - I think it leaves it open for shipping them if you want to, but describing any Doctor-companion relationship as "just" romantic, or paternal, sibling, comradely etc always strikes me as a bit reductive.

Yes, I liked that line too...
