Soooo main plot point that I'm compiling is that the main four - Jengo, Mudiwa, Rahim, and Thairu - get messages from beyond by the deceased characters that take them under their wing as their 'charges'.
For Ikeena, however, he cannot communicate with his great-granddaughter outside of sending well-meaning visions or advice through those visions. The reason he takes her underneath his wing is because of her relation to him. He wants to guide her down the path of righteousness, and knows that she's the glue that really keeps the Four together in the end.
I'll also be doing Jengo, Rahim, and Thairu after this!
