So, if you watched the newest episode of III, you would know that bow is actually a robot. And that leaves me with a theory, bow has been a robot all along, or a bow-bot. In the first season, we see her break out of a METAL box. Robots have incredible strength, so because she's a robot, she was able to get out. Next, in the II 1 finale, it was said the Mephone's exploded and killed bow, but what if it was the opposite. Most phones are waterproof, so maybe bow wasn't and exploded the 2 Mephones. Then in II 2, Mephone said he couldn't recover bow because she was dead, but maybe he couldn't recover bow because she was a one-in-a-kind robot that couldn't be created again. But you might be thinking, what about ghost bow? Maybe it was all marshmallow's imagination, and the only real ghost was dough, pretending ghost bow was there so he wouldn't be forever lonely. Or ghost dough was also just marshmallow's imagination. And then in Invitational, bow survived a boat crash that caught on fire, no object would survive that, but a robot might. Piecing this all together makes it VERY likely bow was a robot all along, pretending to be an object, working for (most likely) steve cobs to spy on Mephone and to grab intel from him to find a way to stop him. But i don't know, its just a theory. Tell me if you think its true!!
