Bolin might have missed a few things since he wasn't sure what Lin's request was all about. But, he was curious and bored, which was probably a bad combination. Besides, if it was dangerous enough that Lin was saying to bring the spirits and potions as a precaution, could he really turn them down? Besides, he wasn't planning on going on the MoI anyway since he'd definitely be useless there. And he DID want to help.

So, while Bolin wasn't sure what he could do about these items, he showed up anyway. He had Chi and Ping with him this time, knowing that he hadn't spent time with those spirits as much lately.
