Tom is a scientist who's alone in life, no wife, his family isn't there and he doesn't have any close love... he can't stand this loneliness anymore..

Tom used his scientific knowledge to create something that will help him get out of loneliness.

Tom doesn't know how he created you.. with real memory, real feelings, independent actions.. like a real human.

You left the capsule seeing how Tom looked at you horrified, without believing how... but you know perfectly what you have to do.
