Harvey didn't follow. At least not with the giant metal body that was his body. By this point it was probably obvious that he was no mere robot, so the disguise wasn't necessary. Still this bot had his stuff, so when the group left to the mansion Harvey went to stash the body. And where else to hide it but the last place anyone would look: A garbage dump. No self-respecting person would hide out here, but Harvey was taught that respect came third towards success. And besides that, it's a lot harder to hide when you're a large clanking robot.

After trashing his body, Harvey activated his Detect Left and followed the marks back to the mansion. It was a nice place, but far from subtle. Harvey wouldn't be surprised if half the town saw this ragtag band of misfits head here. Security was nice, but the best security couldn't beat simply not being found. He'd guess that it'll take the Inquisition a day or two before they infiltrate the estate and do whatever it was they were doing in the first place. And when that happened, that's when this little party needed to figure out what to do with themselves. 

As far as Harvey could tell, these people were helping the kids out of charity. A nice thing to do, but until they wake up Harvey couldn't be certain if they were saving kids or harboring criminals. The Inquisition were a shady bunch, but they don't get kicks out of torturing kids. Even if their goals with these kids are still vile, no one knew enough to make any solid accusation. Everyone was so eager to be heroes they don't even know who the true villains are...

Harvey never announced his presence, but neither did he try to hide. He just sort of... Showed up with everyone else, and headed strait towards the kitchen. He even sung a jaunty whistle took, his ethereal form casually floating a few feet off the ground. He stopped one of the many maids and spoke to her. [b]"Mind directly me to your kitchen? I'd like to make myself a drink."[/b]
