In the latest Transformers movie, one of the bots has a time-bubble gun which slows time in the blast radius.
In one scene, Megatron was caught in it and then one of the Autobots shot a bunch of bullets into it and of course the bullets stop as soon as they enter the bubble. When the bubble is released, all the bullets hit Megatron at once. This made sense to me.
In another scene, Mark Wahlberg is caught in the time bubble (while free falling) and then Optimus reached into the bubble and grabbed the humans to save them.
How come Optimus hand was not affected by the time bubble?
