Though Uria claimed it was a coincidence, saying the design was functional, it seems likely the ship is modelled in some way on Datura. The two spherical units – the mid-deck and the re-entry capsule – are lined up against each other, not quite overlapping. With the garden as a buffer separating them, either sphere is effectively turned into an oval. Ovals have recurred through the history of our contact with Datura, and modelling our ship on this form seems an implicit way of signalling, at the very least, that we have intercepted the contact, and are attempting to respond.
