Felicity loves science but genetics are science and she's pretty sure whoever her dad is, he sucks- inherited brains or no. Tony Stark knows he's changed but his past hasn't. What do the two geniuses from different worlds have in common? Whatever it is, it's thicker than water. From saying goodbye to hello again, where do the choices we make lead us? And can we go back again?
