Question re "little hint" in Book 2 of what is yet to come

I've heard rumors about this "little hint" but have yet to see the 
actual interview in which JKR actually makes this comment...

But if we're speculating:
"Justin was carried up to the hospital wing by Professor Flitwick 
and Professor Sinistra of the Astronomy department..." (CoS 11)

Professor Sinistra is barely mentioned in the books -- but being 
that she's the astronomy teacher (and we know how JKR likes to play 
with the significance of her teacher's names...) could her name and 
station be a hint at things to come?

According to this fixed stars site 
(http://www.winshop.com.au/annew/Sinistra.html), Sinistra is the 
star on the right hand of the constellation Ophiuchus -- the Serpent 
Bearer. In this case could, Sinistra being the right hand of 
the "serpent bearer" indicate that there's more than meets the eye 
to this mysterious professor? 

Also included on the site, which sounded quite eerie when translated 
into Potter-terms: "When Ophiuchus, encircled by the serpent's great 
coils, rises he renders the forms of snakes innocuous to those born 
under him. They will receive snakes into the folds of their flowing 
robes, and will exchange kisses with these poisonous monsters and 
suffer no harm." 

If Ophiuhcus, the serpent bearer, could represent LV, the image of 
him rising and those born (reborn into his following?) under him 
will have snakes [the dark mark??] in their flowing robes is a bit 
forboding. Also, the image of them kissing snakes or as they are 
described, "poisonous monsters" evokes images of certain kissing 
dark creatures whose trustworthiness we've been warned about for 
three books now. 

However, one must also take into account the other story regarding 
Ophiuchus -- Mythology dictates that this constellation is actually 
the body of Aesclepius, a known and supernaturally gifted healer, 
one whose greatest medical achievement was actually bringing someone 
back to life. Could Prof. Sinistra be useful in healing? 
Interestingly, Aesclepius was killed by Zeus while in the process of 
bringing Orion [The constellation that houses *Bellatrix*] back to 
life.

This is just me going out on a limb, but I do think that it's odd 
for JKR to pick *this star* (not a particularly bright or well known 
star) out of the thousands of charted stars for her Astronomy 
teacher...
