Reformatting the dig request gives the following:

dig +trace @athena -x 10.0.2.252

; <<>> DiG 9.3.4 <<>> +trace @athena -x 10.0.2.252

Since this server can't reach the root servers, this makes sense. But
apparently it isn't following delegation.

You've given dig the wrong arguments. You gave it two queries,  
indicated above, neither of which is what you wanted.

Try this:

dig @athena -x 10.0.2.252
