In elasticsearch with replica of 1 when a node goes down one other node is  
still receiving the writes. What happens when the failed node comes up and  
has inconsistent data? Could reads return inconsistent data for some of the  
queries?

When a failed nodes comes up, the cluster will start a recovery of the  
indexes on the node, and for each index, a node with obsolete shards will  
receive the latest shards. During recovery, the shards are not open for  
read.
