Unusually this week, one unclued light includes the theme word which can also be linked with all the other unclued lights, which include a pair. One light is made up of two words, -another of three. Ignore an apostrophe. 33D requires solvers to imagine that an apostrophe s is there, too! Brewer confirms the theme. Ignore two accents.
