Frame is much smaller than the previous ones, indicating a quick change/action.
Grimmsy remains as he was, expression much the same. He seems to be comfortable in it, as if this is what he was expecting/hoping for in terms of himself…in the sense of mission accomplished, maintaining the proper respectful solemnness, etc.
Spirit-form man has gazed back to Grimmsy from the “speech bubble” that was above his head in the previous frame, said bubble now faded almost entirely as if – whatever it was – it was mostly insubstantial at best and has/had a very limited lifespan. His expression is still confusion, perhaps expecting to see some sort of explanation in Grimmsy, or perhaps just the remnant of a quick reaction.
