Sitting shark at left is handing over a somewhat irregular henua to an armless figure, who is he? Is it really henua?

This composition is broken up into three glyphs in Q. There a bent 'finished' elbow ornament corresponds to the irregular henua above:

The irregularity in the H henua probably corresponds to the bending and tapering end of the elbow ornament in Q. We have seen this type of elbow ornament before, in the week of Keiti. There the impression was that the ornament represented images of the orbits of the planets. Orbit or henua, what's the difference?

In a frame of reference where 'sun-cats' mark cardinal points it is easy to misunderstand and believe that the henua (seasons) between these points are straight as rulers. But in reality they are slightly bent, continously changing. The tapering end of an elbow ornament might be a sign of the moon and mean darkness, especially if we include the bend.
