Re: At the Exposition Seats
As Bellgrove delivers the Vril agent to Directeur Forget, Grimsby heads back to the grandstand area, moving behind them to the other side. If he tried circling around the way the other Vril agent had gone, he might not catch up with him in time. This way, he had a chance of cutting him off before he could get into position to use a lightning gun. Fortunately, the lightning gun had a limited range, though, to be on the safe side, it'd be wise to assume the Vril gun had a greater range than Mercy's.
It had to be Grimsby, because only Grimsby had seen the man. Approaching the end of the hedge that separated the building area from the field, Grimsby had made sure that no one was lurking in or behind the 5-foot high hedge. The five buildings that formed the government complex were built in a C-shape, with the two 'corners' placed at an angle. The hedge extended to the end of the far 'stem' part of the C. There was a park beyond that last building that put the next nearest building almost 50 yards away. It was unlikely that the Vril agent would have gone that far, especially since he would have been easily spotted crossing that park.
Along the back of the government building there was a main door, making the building appear to have two faces, with a few small trees at the start of the park and several shrubs and bushes and flowers in a flower bed along the building. That was the most likely approach for the Vril agent once he circumnavigated the government buildings.
While it was possible for the Vril to come between two of the buildings and approach the grandstands across the commons, that approach would have made sense if he felt desperate. That hadn't been the tone of the conversation between the two Vril, though.
Grimsby could now use the hedge to hide from sight of the Vril if he approached from that direction.
