I love Shiro and Louis' CR a lot and boy am I looking forward to some fallout from this month's plot. Shiro is definitely someone Louis trusts enough to talk about his past to, so that's a convo that's likely going to end up being had before long. He'll also be interested in helping Shiro dig up info on Sodder. Let's help the trapped kid! I'd say he could try and help Shiro deal with his "I'm fine" thing, but let's face it, Louis does that all the damn time too.
