As many of you all know "SPOILER" Conclusion for ACT 2, Allies and Soviets will be defeated by Yuri activating mental omega device. I think after activating it paradox will fall under Yuri control or at least epsilon control (Assuming Yuri is killed by Soviets in Moskow). In battle section of paradox engine below air attack paradox has bonus damage towards Norio and Uragon. This leads Norio is joining Foehn in Act 3 after the defeat of Allies.
My CONCLUSION IS:
The paradox engine is gonna used by epsilon against Foehn in Act 3.
Norio will not be affected by global mind control and will join Foehn.
