Why, thank you very much for the compliments! And yes, getting into the tower is assured; Elizabeth's daddy makes frequent trips to the tower anyways. I didn't want to extend that offer until the CS was accepted, though.

As for the entrance it'd be easier if one assumes that Elizabeth was taken there personally by a fancy car or something, hence the lateness. After all, a Blake would never take a common bus! *arrogant hair flick*

I'd also like a quick chat with you about Elizabeth and the staff under the Blake household, and how they might play a role in the plot...but alas, I am a touch busy and will have to PM you later about it. Until then, assume the servants dropped Elizabeth off in the lab on her own because nothing could possibly go wrong, right? :P
