Inderpal Kumar:
Would Indy know Gnat?
*shrug* Likely, Shar would not have mentioned him specifically to you, Indy. But, if you asked about him (not sure where you would have gotten the name from originally), Sharik would tell you that she knew him as childhood friend from Gaargir (it's not a secret or anything as far as she is aware). And that he was a scientist or archaeologist or some such now. Even got some fairly prestigious awards, apparently.
But. honestly, Shar mostly remembers stuff like family dinners and such from a few decades ago. Oh, and this one
epic food fight in middle school...
With respect to the number of connections: you can have more than two, but after the second you don't get more skills or anything (i.e. no mechanical advantages). But in the past, Starmaster has never stopped anyone from extra connections that people wanted to have to just connect.
