Yeah I also was animated by the convincing way she said that sentence! If I were Livia I wouldn't mess with her...
First of all, it is an imperative [command] and the verb usually goes to the front in such statements and secondly, placing the verb last is not obligatory anyway.
(Working off the guess that you mean verb rather than vowel) The verb doesn't have to be at the end; it simply tends to be. Commands like da often show up earlier in a sentence.
