Corrected entry: Tig thinks it's Opie driving the truck. Problem: When Donna stops at the stop sign, Tig has a clear view of the driver. Also, when he pulls up behind her, it's obvious that Donna is much shorter than Opie and isn't wearing a hat like Opie always does. Tig doesn't realize it's Donna until he pulls up beside her.
Corrected entry: When Jax goes to see the truck driver in the hospital, he's in a gown with blood all over it and blood on his face. The doctors would clean a patient up and certainly don't make a patient wear a bloody hospital gown.
Correction: Just before Jax goes into the hospital room he sees two guys leaving. They had just been in the room and beat the guy up. That's why he's covered in blood.
Corrected entry: Wendy has Jax's baby 10 weeks early. When the baby is shown in the NICU, it's very obviously a doll. No movement, nothing.
Correction: Tara tells Jax that Abel is 10 weeks premature, and he's seen three times during this episode. The first time is after Jax exits the hospital, and we do see Abel's movements in the incubator. The second and third time we see this tiny preterm baby are right before and after his open heart surgery, and Abel is sedated and intubated, so of course he's not moving. There is absolutely nothing obvious which actually reveals to viewers that Abel is only a doll.
Corrected entry: A BMW is towed to the shop with a buck (male deer) implanted through the windshield - the back half protrudes from the hole in the glass. An employee uses a chainsaw to remove the carcass in pieces. Later, the head of the buck is pulled from a box, and is seen to still have its sizable antlers. These antlers would not have remained attached as the head passed through the windshield - they would have snapped off. And even if they had not broken off, the windshield's damage would have been significantly different to account for the antlers passing through it.
Correction: I would hardly call the buck's antlers "sizable" (having only 4-points and being narrow). They certainly wouldn't have broken off, and you can see the buck's body is wider than the antlers, so the hole size and damage in the windshield is based on the body, not the antlers.
Correction: After he kills Donna he meets with Clay and tells him about Opie saving his life in the warehouse. He says he didn't know if he could kill Opie so he was afraid and didn't look when he shot. And he didn't know it was Donna.
