Continuity mistake: It was daytime when Bill took the kids to the ATM and questioned them regarding Liv's whereabouts. When Liv picked up the kids and was backing out of the driveway, the sun was setting behind the house. As she drove down the straight road (she didn't make any turns), the sun was shining brighter and then some of the trees on the opposite side of the road cast shadows in the direction of the sun SETTING.

Continuity mistake: The campfire's distance from the tent does not stay the same. When Mason and Mason Sr are roasting marshmallows and making S'mores, the campfire is close to the tent. Overnight, the campfire looks about the width of two tents away. In the morning, the campfire is close to the tent again (less than the width of the tent). Mason Sr's boots are outside of the tent in the morning, but he did not wear boots when walking through the woods the day before - he was wearing brown (hiking?) shoes with black trim and laces. Mason Sr's clothes also change from walking through the woods (t-shirt and shorts) to evening (red/gray checked shirt and shorts) to morning (red/gray shirt and jeans). During this time, Mason's clothes stayed the same until morning when he put on a different jersey. (01:10:27 - 01:11:40)
Continuity mistake: The art/photography display at UT and the background change a few times when Mason is removing his photographs and talking to the woman. The photos along the right side of the display disappear. After Mason removes two of his photos, it doesn't look like the third one is still posted, but after the woman leaves it is visible. The backside of pictures show up through the metal display some time after Mason removes the first two pictures (but were not there when he first removed his pictures). A lot of people are moving around in the background when Mason and the woman are talking and two girls in blue shirts were there the entire time, but when the woman walks away the people in the background are gone.

Continuity mistake: The views inside and from the SUV when Liv and Carol picked up the kids to leave Bill are awkward. Even though Carol gets into the front passenger seat, she is not visible afterwards - views of Liv driving and of the house out the front passenger window should have at least some part of Carol visible, but she isn't. Liv yelled to the kids in the back seat to put their seat belts on, but the way the kids were positioned was not conducive to wearing a seat belt. Mason was sitting with his head and back a few inches away from the back of the seat and halfway onto the center. Samantha's head was past the headrest and her shoulder was partly on the headrest; her body appeared to be at an angle in the corner against the door. (00:56:50)
Continuity mistake: When Mason is driving to the University of Texas, the road behind him is at an angle that doesn't match the slight angle of his truck. (02:03:06)
Answer: She is divorced from the dad. When Mason's mum leaves him with her kids she says that she has contacted their mother and child services.
