Initial Visit
After riding up the elevator with Gordon, Akizet sits down with him at a table, Gordon places a small metal box on the table. Akizet talks about the Call, how, after 32 years, has only reached slightly past its full length, and wonders if it is even comprehensible to understand; before Funfriend cuts her off from saying something, presumably the thought that maybe the Call shouldn't be comprehended. They conclude with talking about what it could be, and who Gordon could tell about this.
On the elevator ride down, Akizet casually mentions that an experimental corrucystic to bright lightning converter exists, and that she can give it to him, if he and the FBX help the obesk track the Call. Gordon obviously baffled by this information, stops the elevator and demands that she tell him more. He then concludes that he can't accept her offer without confirming things with the FBX beforehand, and that she should hang on to that offer.
The elevator then grinds to a halt in the lobby, and the recollection ends.
