[spoiler]Today's quote:
Ep #891 - Megan - 'It MUST be incredibly old.'
From "Robservations 4/14/03 - 890-891 - The Box Goes Whoosh; the Chosen Ones"
Barnabas is very charmed they've come, and admires Megan's locket. Philip explains that he found it in an odd lot he bid on at an auction. Barnabas asks if he knows the meaning of the symbol--it's the sign of the Naga, the creature without a soul. Megan says she isn't sure she likes that. don't worry, says Barnabas--the same sign is carved on that box over there. Megan goes to check it out, as does Philip, who says he's never seen one like it. It must be incredibly old, comments Megan, and Philip can't guess what country it's from.

Unlike the previous examples in the slideshow so far, today's installment doesn't use "MUST" as an imperative. It's the "expressing an opinion about something that is logically very likely" meaning. And just to change things up, we'll be throwing in other examples of that use from time to time...
