what does marco ask eddie to do at the end of act one? what does marco do afterward?

Marco asks Eddie to lift a chair from a certain position. Eddie is unable to do it, but Marco is perfectly capable. Marco holds the chair over Eddie's head as a sign of warning.

"Marco Can you lift this chair?

Eddie What do you mean?

Marco From here. (He gets on one knee with one hand behind his

back, and grasps the bottom of one of the chair legs but does not raise it.)

Eddie Sure, why not? (He comes to the chair, kneels, grasps the leg, raises the chair one inch, but it leans over to the floor.) Gee, that’s hard, I never knew that. (He tries again, and again fails.) It’s on an angle, that’s why, heh?

Marco Here. (He kneels, grasps, and with strain slowly raises the

chair higher and higher, getting to his feet now. Rodolpho and

Catherine have stopped dancing as Marco raises the chair over his

head.)

Marco is face to face with Eddie, a strained tension gripping his

eyes and jaw, his neck stiff, the chair raised like a weapon over Eddie’s head – and he transforms what might appear like a glare of warning into a smile of triumph, and Eddie’s grin vanishes as he absorbs his look."
