Venus Versus Virus/Headscratchers

• Why did ADV have to get voice actors for the dub that sound almost exactly like the ones from the dub of Sailor Moon? Lucia sounds like "Michelle". Sumire sounds like (a slightly higher pitched) "Mina". Laura sounds like "Rini". Geez, my ears...
• Lucia in the first volume of the manga. What's with her reactions? It's..Creepy. Also, she's sixteen (or is it fifteen)? She looks nineteen at best.
