Appropriation

Appropriation is an Institute radiant quest in Fallout 4.

Detailed walkthrough
Talk with Evan Watson in the Advanced Systems part of The Institute. He'll tell you he's impressed with the Brotherhood of Steel's technology and that The Institute could learn a lot from their technology. He asks you to go to the surface and find some blueprints for him, taking and bringing them back. He says there's a small Brotherhood salvage team that has some of these blueprints, which is where you'll need to go to find them. When at the location, a small team of Brotherhood members will be guarding the blueprints, and will become hostile if you attempt to take them. Kill them and take the blueprints, and return to The Institute with them. When giving them to Watson, he can be pushed with a speech check to give a reward, which if successful, will be 4 fusion cells.
