Where were the chain link fences, the metal detectors?

铁丝网栅栏在哪儿？还有金属探测器呢？

GITTLESON: Yeah, a foot chain link fence to keep the wolves out.

对，用铁链围起来栅栏，防止狼进来。

So she watches through this chain link fence. It's this literal thing separating them, but even if it weren't there, there'd be no crossing from where she is to where they are.

所以她透过铁丝网围栏观看。这是将他们分开的字面意思，但即使不存在，也不会从她所在的地方到他们所在的地方。
