What is the last gift the narrator receives from Isaac in the novel, All Our Names?

Isaac gives the narrator a passport under the name Isaac Mabira, but there is no picture. Isaac tells the narrator that it was done purpose and that the narrator should put his own picture in once he reaches Kenya. This enables the narrator to go to America and to escape the bloodshed going on in Uganda. As this is Isaac's final gift to his friend, it is acknowledged that the real Isaac will possibly die during the remaining parts of the revolution but Isaac does not mind this as long as it keeps his friend safe.
