With as little time as I've had lately, I'm not even bothering Pm'ing this, this should allow you to do what you can in the sewers. I'll leave as much of the sewers as you can handle to you, Let's just make it convinent and have us come out near (if not on top) of where they were battling.
Miles has no interest in what the ghost "Rosancratz" was trying to do, He could tell by the ghosts grin that he was just up to some foolishness. It might drive Cinni crazy, but for now he just had to keep going forward with the plan.
"Cinni, never mind him for now, I need you to use these ears of yours to pry open this sewage drain." Cinni had stopped complaining mid sentence (he had been still taking quite the storm, up until this point.) Happy to have something distract him from the weird ghost. "You got it boss!" Cinni replied cheerfully and with his ears was able to pry open the lid with relative ease. With the sewer drain open, Miles looks towards Samantha, and then towards Rosencratz, a brief flash of disappointing showing up on his face when he gazed upon the ghost. "Well, the sooner we get this done, the bett-" CRASH! A large almost blinding flash of light followed by a noise not unlike a sonic boom suddenly emerged form the silence closer to the center of the city. MIles remained unshaken, even if his partner and new companions seemed to react differently. "Cinni, can those ears of yours figure out where that sound came from?" Miles inquired.
"Yes It shouldn't be to hard to to, I have a fairly good sense of direction." Cinni smiled and then floated on to MIles back, ready for their journey in. MIles to no time to consult his new found allies, and instead went straight into the sewers, almost as if Samantha was just as much of a ghost to him as her partner.
