That wasn't good. It might have been whatever her magical knack was supposed to be, or it might have been just her talent for observing people, but even not being able to see around to Temeraire's ventral side she could tell he was having trouble.

She looks to the heavy cables attaching her Grungust to Temeraire's harness. They were attached to winches that theoretically would let her move around, though she had been explicitly told it was risky by the engineers. Still, given a choice between letting Temeraire get stabbed and possibly unbalancing him, she chooses the latter option. Making the Grungust draw its sword now that its fist had been winched back into place, Kusuha carefully begins climbing the heavy machine down around the dragon's right side to try and get within reach of the troublesome rider.
