Randy / Randi

[Boomstick]

In Chapter 19 Part 1, when michael comes to after his surgery he awakens to Hope by his bed side. Hope then asks who Randy is. Michael seems to want to change the subject mighty quickly. I missed it the first time I listened to the chapter. So who do yall think he, or she, is/was. We know that Michael is an only child so it cant be his brother or sister. Maybe though, i'm just spitballin here, it could be a step brother or sister, his best friend/oldest childhood friend. Someone he served with. I believe it is someone he is really close to or at least was. Michael is a character that keeps everything close to the vest, matter of fact the only time he actually "slipped" up was when he was under the influence of anesthetics. What are y'alls opinions?
