The whole raiding the grove bit is stupid. So stupid that the drow allegedly questions your motives afterwards, not really understanding why you went along with it.
If you actually play the dialogues as a self-centered driven Tav, it's not stupid at all.
You go with your tadpole to the druids and their "healer" tries to stab you with a deadly poison. They are lead by a Shadow Druid, cult which despises all society and preaches anarchy. They are also in conflict with a bunch of weak Thiefling hobbos who are living off the druids and have no strong leadership to get them even remotely prepared for the road ahead to BG. The hobbos want you to risk your neck and go kill the goblin leaders, as if that means the rest of the road to BG will be a stroll.
The goblins on the other hand control the Nightsong ruins, the nearby town and have competent leadership. Not only this, but when you go to their camp you meet a powerful Absolute entity which they serve, entity which is in some way linked to your tadpole. It's clear that from all you've learned so far, the Absolute is the only one who actually has good information on your tadpoles.
At this point, why the fuck would you do the Thieflings dirty work when you could easily ally with the winning side AND get into Absolute's graces. What do the useless thieflings or the clueluess druids have for you? The stupid choice here is taking on all the risk to serve a losing side which has zero answers for your tadpole problem. That's what's stupid, the sort of stupid that a moron like Wyll would do.
