Lori turns back to face McGarrett (camera shot from behind), and in the next camera shot (camera shot from in front) she turns back to face McGarrett again.
Continuity mistake: When Steve and Danny go to Dr. Yang's office and find evidence of a struggle, they follow a blood trail out the back door.

He only has one glove on before the camera angle switches to the view from behind him, then suddenly he's wearing gloves on both hands as he reaches for the wallet.
