*Before going to Patrick O'Rourke's wake, Remington touches his tie with his left hand. Twice. The first time there is no ring on his hand. The second time there is. And it's the only moment when the ring appears in the episode. Besides, it's the third finger of his left hand, which probably means it's Mr. Brosnan's wedding ring.
*When Remington falls from a pier, he's wearing a gray checkered suit and a reddish tie. When Laura visits him in the hospital, he's wearing a black suit and another tie. If, as the doctor says, they have no idea who he is, Steele's clothes must be somewhere at a hotel, where he was staying before the attempt on his life. And the suit fits too well to be borrowed. Later, when he regained his memory, they probably found the hotel and his suitcase; that can explain the fact that in the end of the episode he's wearing the same raincoat he wore in "Blue Blooded Steele"
