I regard this as one glyph, not two. There is so little space between the left and right parts. A kind of proof that I am right is delivered by counting to 99 glyphs in this moon calendar.

We can recognize toki (left) and at right the 'sleepy old bird' (moe). The problem is the middle part (GD57). Is it some sort of flow? That is the idea we arrived at in Mamari:

Evidently there is a continous action or proceeding of events:

Ea2-24	Ea2-25	Ea2-26	Ea2-27	Ea2-28
e tagata tu ara i te toki - kua tua koia	e tagata mau e toki erua e	ka rere te toki - i te henua	rere te toki - rere ki te verega	rere te toki rere ki te henua e tagata tagi karaga era e

The word karaga = uproar, row. And tagi = to cry, to weep, to moan; tatagi, to cry much; to cry lowdly: he-tagi te karaga. A bawling, vociferous person = tagata rava, tagi karaga.(http://www.rongorongo.org/vanaga/a.html)

This is not much to go on.
