After Sofia runs off from the phone where Deegan shot at her. We see Pete hang up his phone.
Deegan then asks the operator to run a trace on the open line.. Accept it won’t be open anymore because Pete hung up.

When Frog is running around in chass of Mrs. Rose He almost slips and falls.

When Frank is sitting down with sandwich in hand he tells MacGyver he doesn;t like fish, but we soon see him pick up the fish Sandwich as tho he is about to eat it.

Colton gets shot in the fish factory, but afterward appears fine and using both arms with no effects until the last scene where we see him with his arm in a sling.

when colton and MacGyver crawl under the merry go round watch when MacGyver comes up on the other side you can see the gypsy girl right behind him when supposedly the bad guys are taking the black corsage out of it right at that time. It was obviously shot at the same portion of the merry go round at different times.

when mac and frank are checking with the security guard he says sophia never showed up today indicating that she worked there as her badge said she was in research but earlier when she was walking she seemed surprised and relieved that she was at the western division of the phoenix foundation, If she worked there every day she would know its location.

when they are eating at the cafe frank is complaining that they gave him a fish filet sandwich but later when hes talking about the insurance money he clearly has a cheeseburger

Not sure if this should be a nit-pick or not...did anyone else catch a mike in the upper right hand corner when the bad guy is chasing Mac outside and Mac runs under the big glass wall and the camera cuts to the bad guy (and the mike) running under the same glass wall? Around the 39 or 40 min mark I think
