BloodShard

Alright here is what I am curious about. So we know that Szeth was killed and brought back. My question is do you think that Szeth now qualifies as a Returned?

A few quick questions/theories about how Nightblood interacts with Stormlight: 1. Presuming Nightblood can be fueled directly by stormlight, does that mean in a highstorm Nightblood would have limitless use? 2. Since Szeth's Honorblade gave him the ability to hold stormlight do you think that Nightblood will grant the same ability? 2b. If not, then will Nightblood be able to suck in stormlight directly? From sources such as spheres, the highstorm, and when hitting shardplate? 3. What do you think happens if Szeth is wielding Nightblood and the stormlight fueling Nightblood runs out?

Now this may just sound crazy, but is it possible for Kaladin to keep the honorblade and use 2 shardblades? I know that you cannot wield 2 dead shardblades (Otherwise someone would be doing it), but would still apply to an honorblade and a living shardblade?

Presuming that Nightblood can indeed be fueled with stormlight, do you think that means that if Szeth were fighting in a highstorm then nightblood would have unlimited use during that time? Along that note, do you think that by wielding nightblood Szeth will still be able to draw in stormlight? Or do you think that Nightblood will pull in stormlight directly?
