Continuity mistake: Cross is holding a normal striker fired (no external hammer) Glock handgun against the head of Ant-Man. In order to save his life, Hope orders the ants to block the firing mechanism of the gun, and they block a suddenly-visible hammer on the Glock. (01:26:00 - 01:27:00)

Scott Lang: My days of breaking into places and stealing shit are over! What do you need me to do?
Hank Pym: I want you to break in a place and steal some shit.
Scott Lang: Makes sense.
Trivia: In the final scene, Luis is talking with Scott about his friend's date who met up with The Falcon one time. Luis stated that The Falcon was asking that he is looking for a guy and the woman talks about the guys she knows. One of the guys Luis said she mentioned is a guy who climbs walls. This is a clear reference to Spider-Man, who is set to appear in the Marvel Cinematic Universe very soon.
Question: SPOILER: When Scott invades the helicopter to stop Cross, Cross appears in the Yellowjacket armour. The Yellowjacket armour before this was placed inside glass casing and was miniaturised. My question here is, how exactly did Cross get the Yellowjacket armour to human size before putting it on?





Chosen answer: The suit was built human-size and then shrunk using Pym particles. The same technology can also be used to grow objects. Cross was shown to have a hand-held device earlier in the film capable of shrinking, so he either used this device, or activated the suit's built-in growing/shrinking technology.
