1. How will the rest of society accept their relationship?
2. Won't the company that bought Silas' commission want him back since he's technically their property?
3. Will Silas' malfunctions not get worse over time?
4. How would MC and Silas... uh... consummate their love?
5. Would they?
☆
1. Like the two lab coats do in the friendship ending; with pity, condescending patience, and awkwardness. Probably thinking 'how pathetic, she must have been very lonely to consider a tinman a friend' or 'yepee, yet another self deluded dreamer who think its machine feel anything for her' and sometimes, 'she's probably crazy and dangerous'.
2. Absolutely. So they have to elope. ˆˆ And to scavenge from bot facilities, rerout power sources, and live in shady hacker dens to sleep and work. Or Silas can decide to be transfered into the MC's home computer (granted that those exist and hers have enough space to store him, live or powered off) the time for those who search him forget about him, when he can then be transfered into a new body (buying a bare bone discount shell of his base model could do).
Or the MC can make a huge bet while Silas is not online by buying him with a loan shark's money or by selling her house and taking a ridiculous hugebank credit. The fact her mental health may depend on it + Silas is too quircky to do reliable work for them but it still had cost them a lot + the MC is willing to return them their money and take judiciary responsibility for the tin, would convince them to sell, no? Silas can make a lot of relatively shady money to pay the dept, afterward. I'm sure there are more than one or two ways for a creative girl and a solid bot to do that.
3. Very probably. And that could be the plot of another story: how will Silas readjust his human safety protocols to fit among humans and bots now that he knows he can do it?
4 and 5. Five routes. One: Physically. Who cares if he is built like a Ken? I don't remember the MC complaining that Silas had a dry mouth or that he tasted toxic or motor oil. Two: pink plastic bunnies. Third: electricity and music tingles XD. Fourth *blushes*: harmless code tweaking for happiness loops (self combust from shame). Fifth: they play poker and chess. The Ace way.
