Happy Late Valentine's Day, Professor!

... This made my heart hurt so much T^T

So storytime for those who don't know the story:

Walter and Josephine (his wife) were living normal lives. Josephine was about 7-8 months pregnant when the nuclear war happened. His town got blown up and he tried to protect Josephine. Unfortunately, he couldn't. He lost his left arm and leg and... well, his family. He built the robots to keep him company and tries to be happy every day. Valentine's day was when he and Josephine got married. So, the bots saw him in his lab inventing to take away the pain. They decided to help him be happy again by showing their love for their father. 

Happy late valentine's day, professor Bolts <3
