I tried to make it as close as possible to his personality in seasons one and two, I ended up discovering that it doesn't make much sense to follow it so faithfully, so...

Think about it with an au. Colin is an ultra-tech robot created by a company known as DHMIS, founded by Roy Gribbleston and Harry Red (LOL). Here, Colin is being subjected to an experiment, where they color him as an AI to live a "normal" human life. So much so that he even works as a professor at a technology university.

It has many elements from the series, but I'm not going to release the description yet, I want you to draw your own conclusions if it looks like it after interacting with the bot.
