Really? Lucas, you are in a "lab" and your first instinct is to drink random unidentified stuff? It could poison you. It could be a magic potion that turns you into a tree. Also: you are a guest here. Typically this does not imply you can drink anything in the host's house without permission.

She’s the same age (well, stage of elven development anyway) she’s always been since first introduced in the comic; she’s just short.
