A story about a pace vehicle that suddenly makes an appearance to a vehicle already in orbit:
One of them has spotted us. What do you think its reaction is – surprise or fear?
Surprise first, then fear.
If another appears at the porthole, the first one to spot us was an underling.
There are two of them now, the second one at the porthole is the leader.
Did you notice, one of the others is different?
A bifurcate, a cleavage, a mate?
If you could use one term – how would you describe them?
This could be amusing to see how they react.
Yes, but only for a little while, because it also appears that they can be very boring as well.
What is insignificant?
You wondered how they could best be described
(all) Yes, ARROGANT AND INSIGNIFICANT would really be the best description.
