Neque te teneo neque dicta tua refello: i, regnum Italiae per undas! Spero equidem te in mediis scopulis periturum [esse] et nomine 'Didonem' saepe vocaturum! Dabis, improbe, poenas!"
...from Orberg's CP XL: Dido is telling Aeneas to clear off and that she hopes that he and his companions drown. She finishes this with: Dabis, improbe, poenas!.... which seems out of context. I would have ended it with Daberis improbe poenas! ....You will suffer you wretch...! which seems to logically follow...
Unless I translate it somewhat idiomatically as: You hurt me you wretch!
Am I on the right track...?
