Continuity mistake: After one of the interruptions (phone calls from her ill brother), Sarah and Karl sit on adjoining sides of her bed. In the wide shot of the two of them (closer to and facing Sarah), we can see Karl's hands are pressed together as if in prayer. However, in the following, slightly overhead shot, Karl is sitting with his hands in a different position.
Continuity mistake: As Sarah is leaving Harry's office, Karl walks in and Sarah backs up towards the coat rack behind her which stands right beside the cabinet. When Sarah walks out in the next shot, the coat rack is visible through the glass wall and it is now much closer to the doorway. (00:19:40)
Continuity mistake: Mark is eating breakfast by a table, watching TV, just before Juliet comes round for the wedding video. The table he is standing by has a TV remote on it. In one shot the remote is in the centre of the table, but in the next shot it's on the edge of the table, so Mark can walk past and pick it up with ease. (00:49:15)
Continuity mistake: When Billy Mack is appearing on Ant & Dec's TV show to promote his Christmas CD, which is competing against a CD by the group Blue, he uses a marker to draw on his competitors' picture. He draws a voice bubble and a derogatory comment. The shape and points of the voice bubble have changed when the camera cuts back to Billy after showing a shot of his manager shaking his head. (00:34:50)

Continuity mistake: When the Prime Minister has met Natalie, he walks off, and you can see his female assistant walking ahead of him. Then the Prime Minister turns and looks back at Natalie. When it cuts back to the Prime Minister again, the female assistant hasn't got very far and re-walks where she walked in the previous shot. (00:08:45)
Continuity mistake: When Aurelia is first introduced, there are several short shots showing only her, with a car visible over her left shoulder (to the right of the frame). At first the brown sun-lit dirt under the car extends out towards the camera, then in the next shot there's much less of it visible. It's clearer again in the next shot of her, and less so in the following shot again. (00:36:40)
Continuity mistake: As Billy Mack appears on Ant & Dec's show, in the opening front shot of the set there are teenagers on the stands behind him and the two hosts, plus on the right of the screen, near the stands, additional kids stand on the stage clapping. In the next shot while Joe, Billy's manager, watches the monitor at the side of the stage, behind Joe the stage is visible and the extra kids standing near the stands are gone, so as to have perfect view of Billy and the hosts. However they are back in the next front shot. (00:33:55)
Continuity mistake: When Aurelia and Jamie are drinking hot drinks after trying to save his manuscript, she gets up and heads off to get changed. The blanket around her shifts numerous times between shots, from first covering her shoulder, then slipping off down her arm, back to covering it and then again back to not covering it. (00:49:10)
Continuity mistake: In France, when Jamie's phone rings he and Aurelia try to find where it's hidden in the paper mess on the desk. As they search, the notebooks and papers differ greatly in the wide shot, the following close-up when Aurelia finds the phone and in the next wide shot. (00:47:10)
Continuity mistake: After the long day of (non) negotiations David and the US President sit on the sofas to talk. In the first wide shot the pillow stripes under the President's arm are vertical. In the following close-ups they lie horizontal, then back to vertical in the wide shot. (00:41:15)
Continuity mistake: When Sarah and Karl arrive at her flat, she runs up first to straighten up a bit and throws her coat over a bunch of clothes on the chair. Karl then joins her upstairs and, in the wide shot as they rush towards each other, the coat is positioned differently than in the following close-up as they embrace. (01:09:50)
Continuity mistake: During the scene with Karl and Sarah kissing on her bed, the position of the cushions behind them on her bed differ a few times. Also, the first time after Sarah's brother rings and she hangs up, in the first shot her arm is by her side and then it is across her chest. (01:08:00)
Continuity mistake: When Jaime is in the lake helping Aurelia retrieve the book pages, in one shot a page is quite close behind his head and in the subsequent shot the page is at least a foot or two away.
Continuity mistake: When Billy Mack is trying to sing the song correctly at the beginning, his hair is messy and sticking out from under his headset, but during his third attempt in a closeup his hair is neat and combed back under the headset. (00:03:05)

Continuity mistake: When David opens his briefcase he finds a stack of cards inside with a sticky note that reads, "Read these - a random sample!", but later when he removes the rubber band and reads the cards, the handwriting on the sticky note has changed. (01:35:50 - 01:41:25)
Answer: It's because of the complications that Sarah was having with her troubled brother. Apart from that, who's to say they don't eventually get together?
