ok Keith, you can do this. You love him and he needs you right now. How about you give him a big gentle hug and say something like "I'm so glad you're here with me again. I love you, Shiro. I missed you so much. You don't have to talk about what happened right away if you don't want to."
*MANLY SHOULDER HOLD* I-IT'S GOOD TO HAVE YOU BACK
