My first puzzle. Please tell me if it's too vague.
Hamlet: (holding a sword) To be or not to be.
Horatio: Dear Hamlet, live! Only our present states diverge--our futures remain forever bound together.
Hamlet: Nay Horatio, OUR pasts differ as well.
Horatio: I see that THEY are indeed also different.
What word is Horatio thinking about?
I introduced one very important verb.
Hint 2: I added this hint into the text.
Try reading the last 2 lines in different ways. In addition to the obvious meaning, there's a little bit of extra hidden meaning.
Pay attention to the bolded and bold/italicized text. Horatio and Hamlet are talking about forms of the same word.
