Spider that bit Ele Teara

[daniel san]

Ok guys need your help...

Exactly where is the spider that bit Ele Teara? In the cave where I can find Ele, there are a couple of spiders roaming around but none of them show the sign of being part of the quest (blinking circle above the enemy).

There are two spider enemies left in the cave - one that's just standing in the corner not moving around, and one that moves around. Then there's a zombie troop that's roaming around. Are any of these part of this quest? Or is the spider that bit her somewhere else? I'm really lost right now...
