Eames/Rey/Atticus/Manning: the B&B
Rey nodded at Eames. "Stand back," she suggested to Eames and Manning. "This shouldn't be dangerous, but it might be. Not what I'm doing--whatever the thing is going to do when it's assembled."
Usually Rey summoned things to her with the Force, or raised things, or lowered things, or some other simple motion. This was a little more complicated, but it was within her ability to do with some concentration. The base was already set in place, which helped, and Rey put the face, which Eames had just added, into place, then moved her own piece, the side, in with it.
Last, but not least, she put the top into place as well.
Gesturing with her hands didn't really help Rey, but it did ease a bit of the strain of concentration, so she did that, though to the eyes of an observer, the motions didn't entirely or exactly match what the objects in the circle were doing. Her brow furrowed and her jaw set with the focus required to put the sections together delicately instead of just jamming them into place, but there were no other signs of significant effort.
