链结

链 = 连 + 钅 : Li Qingzhao (li) has been kidnapped and chained down (连) in the anthill's bathroom (an4). Luckily she has a tiny golden harpoon (钅) as a necklace (链) around her neck which she is able to pick up with her mouth, and with which she is able to pick the lock.

结 = 吉 + 纟 : The silk worm and Joan of Arc are in an awkward situation. The giant has pulled the worm so long that she's long enough to tie Joan of Arc to one of the pillars of the elevator's kitchen, and to even make a knot.
