I can answer the drow bit.
By this point there is a significant population of drow living on or near the surface. This includes both Seladrine Drow and Vhaerun-worshipping Drow.
4th edition storyline had an event were a large portion of drow were re-accepted back into the Seldarine which resulted in them returning to their original skin colors among other things. I personally didn't like that bit of story which came along with the deaths/removal of Vhaerun and Eilistraee, both of whom I find as more interestingly developed gods than Lloth. It was basically an excuse to remove not-Lloth drow by declaring them no longer drow. With 5th ed, they've brought back Eilistraee and Vhaerun. I personally would still tend to stat the Seldarine Drow as Wood or High Elves (because they've been on the surface for a couple of generations mostly) but they are culturally in the lore considered drow again.
But to summarize up, there's a significant minority of surface dwelling Drow in the Sword Coast regions. If your Drow is Lloth-sworn....that's another question entirely....but with the growing number of openly existing surface-drow communities it is likely that Lloth-sworn have started sending spies up.
Lloth sworn often raid the surface for slaves, and things, plus your from Menz which is rather close to a mindflayer community. So either you were wondering the underdark got snatched, or got snatched in a raid topside, the same raid that the mind flayers picked up others. as for the tadpoles in the head of those around BG, it could be something else doing that and not the mind flayer.
There is an optional conversation in the ship (talking to everyone is good, and exploring) that occurs to lead me to believe this, especially when combined with a conversation, or a couple off the ship. Though then it gets kinda murky to the specifics. the murkyness is acceptable since we are in the first act, and there is more to come.
