YAY! Romans! \o/
There's a few minor spelling errors here and there, and I haven't gotten the faintest idea whether the Latin is correct, but beyond that everything seems good. You might want to keep the 'surprise' phase going a bit longer, though. Both of these groups are meeting other humans, and the Romans are meeting humans they weren't expecting who know their language. While I can understand a soldier would cut to the point and leave the details to the eggheads, the change from 'wtf' to 'smile' seems unreasonably fast.
