And this sounds strange, but my mum recognises Summer as "that girl who was on The Big Bang Theory" -- she's never heard of Firefly or TSCC o_O
That's great! It means that Summer is getting more exposure outside the sci-fi niche. Your mom, as well as all Australian or American moms, will be Summer's tv viewers once she'll land a role on a mainstream non-sci-fi tv show.
Now i suggest you show your father a few photoshoots with Summer
