Logan has underestimated Quinn here as he does have an army and said army can infect others. Quinn just get ship attack the cruisers one at a time and convert their crew to his shadow army. Put them all in his shadow space them move on to the next and repeat. Quinn will take Jim and Truedream's army for his own.
To be honest, Quinn does have a small army already, with the Demon tier beast infecting other strong beast on the Vampire Settlement's planet, although I suppose with Quinn turning to Cecil means he's going to try and get to the Mermarian planet, which is probably where Sil sent the other Blades, possible even the Amra Planets to help build up a strong army.
We are all forgetting about Galen he's going to have a part in what happens maybe his ability negating ability will come into play it wouldn't have been revealed otherwise and he's made it perfectly clear he won't just be put away somewhere to keep him safe him and Minny are going to cause some havoc
one thing Quinn has in his favor J&J don't know what Quinn did for the Mermerial and Amra races or about them and the shadow beasts I doubt that Quinn will resort to infecting everyone with the Shadow cause that's Immortui's ability from way back in my Dragon System times it's not a good thing and could strengthen him at the same time
