Exceptions To The Octet Rule - Lewis Dot Diagrams

This chemistry video tutorial discusses the exceptions to the octet rule while providing the lewis dot diagrams of the molecular compounds involved. BH3 has an incomplete octet - that is, it has less than 8 electrons. Molecules such as ICl5 and PCl5 have an expanded octet which means the center atom has more than 8 electrons. The last category are molecules with odd number of electrons such as NO and NO2. These will always be electron deficient and contain an incomplete octet at the nitrogen atom.

    Someone help what's happening at NO2 at 12:10? Oxygen isn't donating anything. And given that Nitrogen primarily has 5 ve at the start, im assuming a coordinate bond has been formed with the Oxygen atom on the right? SInce it looks like two electrons have been donated to Oxygen there by Nitrogen solely. If we assume that two have been donated to oxygen by nitrogen on that side, only then does it imply that it had 5 valence electrons in the beginning. Otherwise it doesn't make sense. Am i getting anything wrong?
