AND THEN Steve shows up, Cho tells him how dangerous the gem is, they can't just blow up the cradle. Hawkeye and Black Widow fly over in the quintet and spot a lorry from the lab being used to move the cradle. Cap draws Ultron out and keeps him occupid whilst Natasha goes for the cradle, dropping out of the qunijet on a motorcycle, picking up Cap's SHIELD to return to him - 'I'm always picking up after you boys' - and being awesome. Two bots make the lorry fly and Natasha blows it up to send the cradle at the jet, and Clint catchs it. But Ultron grabs Natasha in a fly by. 'Do you have eyes on Nat?' Clint keeps asking, but he's forced to leave as Cap tells him to get the Cradle to Stark.

Cap ended up fighting Ultron on a train, before he flew off and grabbed Natasha, and Wanda and Pietro joined him to help. Now Pietro gets people out of the way of the de-railed train and Wanda stops it. Then they say DON'T send the cradle to Stark. Cap says it's okay, but Wanda says no, 'Stark will do anything to make it right' and 'Ultron doesn't know the difference between saving the world and destroying. Where do you think he learned that?" Cap can't get Tony on the comms.

ENGLAND: not quite sure where this goes, but Thor meets Eric Selvig outside a university and they go to some mysical waters of sight so Thor can take his shirt off and revisit his vision. He sees lots of things, including the inifnity gems.

AVENGERS TOWER: Tony sends Clint off to go look for Natasha using spy craft and he says 'yeah, i'll find her', leaving Tony and Bruce with the Cradle. Tony found the person protecting the nuclear codes and stuff on the internet: broken pieces of JARVIS. He's put them back together and now... Bruce says Tony wants Bruce to help him put JARVIS into this thing, and Tony says no, he wants to help BRUCE put JARVIS into this thing, because this is Bruce's area. He talks Bruce into it.

SOKOVIA: Ultron waxes lyrical to a captured Natasha. Because he has no one else to talk to. Natasha takes broken tech pieces she ends up with and does morse code spy stuff.

AVENGERS TOWER: Clint gets Natasha's message and knows where she is, and Ultron.

Steve, Wanda, and Pietro show up. They want Tony and Bruce to stop, but they refuse, so Pietro pulls all the wires and plugs out. Clint shoots the glass floor out from under Pietro - 'you didn't see that coming.' Everyone is angry with everyone else. Then Thor appears and zaps the cradle with lightening and the body comes to life.

It's a red, flying man, who stops when he sees his reflection in a glass window. Thor tells them about the power in the gem in his head, that he's had a vision. They question the newcomer. Cap asks if he's on their side, this Vision, who replies, 'it isn't that simple.' Clint tells him to get simple real fast, and Vision says he's on the side of life, and Ultron isn't. That he doesn't want to destroy Ultron because he's uniqute and in pain, but he must be stopped. That they have no reason to trust him, blah blah blah, then he casually hands Thor his hammer.

Cue eveyrone being hilariously gobsmacked. Very amusing facial expressions!

Thor: okay then.

Montage where everyone gets prepared for the fight.

SOKOVIA: Cap says 'Ultron says that we're monsters. That we're everything that's wrong with the world. It isn't about beating him. It's about whether he's right.' This time their plan is to evacuate the city before everything kicks off. Wanda mind controls people to leave and Pietro shoots up a police station to get them moving. Iron Man meets Ultron at the church from earlier. He tries to stall, so they can get people clear, but it turns out Ultron was also stalling. Ultron reveals a machine in the middle of the church.

Bots appear from everywhere. Avengers fight them. Vision attacks Ultron, cutting off his access to the internet. They need to destroy all traces of Ultron, without letting any bots escape.
