Steve tells Daiyu Mei that his father had never met Wo Fat. This is a problem, as FIve-0 discovered video footage of Steve's father in a meeting with Governor Jameson and Wo Fat in 02x01.
Danny tells Steve he should have kept some of the money Doris left him so he could fly first class, to which he replies that he doesn't need to fly first class, yet in the final scene, he is clearly sitting in the first class cabin (there are only four seats per aisle where he is sitting, and you can see that there are six seats per aisle in the next section of the plane).
When Danny is brought to the hospital the medical team does not continue with pressure on Danny's wound once McGarrett is denied entry.
