Book Two Discoveries! [Parselmouth!Harry]

I just re-read book two, keeping my eyes open for "discoveries". 
Apart from all the things that have been mentioned in this thread 
before, I think another potential "discovery" is that Harry speaks 
Parsel. - This is something neither himself nor others had known 
before. After CoS, this power never played an important role again.

Now what could the discovery of Harry's Parsel knowledge foreshadow? 
I suspect that it hints at something that happened the night Harry's 
parents were killed, especially what happened between himself and 
Voldemort: The transferral of magical powers, the mental 
connection,... Maybe Harry got another magical power transferred from 
Voldemort that night?
