You know, we describe Sentinel as a pandemic preemption system, and here we are in a pandemic.

PS：你知道， 将 Sentinel 描述为一个大流行病先系统，而在正处于大流行病。

Such a preemption, like that of a traveller's bag in the rack, was unquestionable; and, for additional evidence, sitting with her knees crossed, she kept one foot continuously moving a little, in cadence with the other, which tapped the floor.
