Michael is at the hospital with Sam as the CIA and the local police arrive. To create a diversion he flees the hospital on a motorbike. As he races around the grounds you can clearly see the tracks left by the motorcycle on the ground where they have attempted a previous take, or a run-through without the cameras rolling.
The grenade spoon is still attached when it lands in the foot well, which means it is not armed.
When Dr Jed takes the bullet out of Sam and puts it into the glass of water, it's a fully formed pristine bullet. A bullet fired thru a car door into a person would be mangled and, most likely, fragmented.
When providing a distraction for Michael to sneak onto the cartel boat, Fi and Jesse are firing silenced HK MP7s. However the distracting fire they lay down is not silenced but rather quite loud.
