心弦

心 = 乚 + 丶 : Marie Curie (xi) uses a shovel (乚) to dig a hole in front of the encampment ((e)n1). She wants to bury her heart (心). To the side are three petal leaves (丶), with which she wants to cover it afterwards.

弦 = 弓 + 玄 : Marie Curie (xi) is getting trapped by black lava (玄) in the anthill's kitchen (an2) and all she has is a composite bow (弓). She plucks the string (弦) of her bow so that the chord (弦) resonates with the lava, causing it to stop its flow.
