Dr. E Shaw, David to Walter, Weyland/Yutani

So, running into questionable items like the image above with the Name/Dog Tag that says Dr. E. Shaw. Makes me think that Shaw is found dead on the planet somewhere. 

The other question is why jump from Ash, Bishop, Call, David to Walter??? Seems odd unless there is relevance to the Blade Runner/Alien connection...

The other item Weyland/Yutani and the whole Colonization synopsis to the story of Covenant. Ridley Scott obviously deems Cameron's Aliens as canon and perhaps the reason for delaying Alien5???
