I have a theory about how (if it can or will happen) Adolin can re-awaken his Shardblade. In Chapter 13, Shallan has this thought: "Wait until Adolin sees a Cryptic in Shadesmar form, she thought, with a full body but twisting shapes for his head." Which got me thinking, what if Adolin actually does visit Shadesmar? Either mentally or fully in the physical, like what Jasnah did to save her life. If he has his Shardblade with him when he does this, will he see the half-dead representation of his Shardblade and be able to interact with it? What happens when someone who isn't bonded to a spren visits Shadesmar with a half-dead Shardblade? Could you fix them by feeding them Stormlight in Shadesmar? Are there any WoB about non-shardbearers going to Shadesmar?
