“The Changeling” is full of instances where characters happen to be at the right place at the right time.  However, I find Scene III, Act iii to be particularly interesting.  In the asylum, Isabella is looking at the different madmen.  When she is left alone with Antonio, he reveals himself to be faking his craziness, and he professes love to and kisses Isabella.  While she doesn’t seem entirely supportive of the actions, she doesn’t do much to fight him, either.  During this entire scenario, Lollio was watching from above.  He escorts Antonio away and when he returns, he is in a position of power over Isabella because of what he witnessed.  Even though this play is “consumed with changeability” there are still moments where location and timing are critical, and this moment is one of them.  Because of what Lollio saw, he is now in a position to take advantage of Isabella in nearly any way he sees fit (and, at that moment, does attempt to kiss her, and calls her a prostitute).  Isabella is married, and of course should not be fooling around with anyone (especially her husband’s patients)—which Lollio knows and will take full advantage of.
