Predictive response
1. Unlikely as the impregnation is currently mapped out be a narrow path, with the payoff implemented in the end CG (not like a Summer Time Saga game mechanic)
2. This would require a redraw off every single CG, it will not happen.
3. Think Ken is planned (at least a method of inviting him to the studio when down the Samantha path) think Master Zhen is complete, but there will sure be more share content with other characters...
