Chekov: I don't understand what's so special about this region of space.
Mr. Spock: Picture it this way, Mr. Chekov: we exist in a universe which co-exists with a multitude of others in the same physical space. At certain brief periods of time, an area of their space overlaps an area of ours. That is the time of interphase, during which we can connect with the Defiant's universe.
Uhura: Mr. Spock? We WILL be able to retrieve the Captain at that time... won't we?
Mr. Spock: Yes. However, the dimensional structure of each universe ...

That's Some Web, That Tholian Web!
5 May 2014 | by (United States) – See all my reviews

This is a great episode. It has all the really cool elements. It has a worthy adversary, the Tholians. It has Kirk caught somewhere between his physical being and his molecules spread across the universe. It has McCoy viciously attacking Spock and his decisions, time after time, questioning his very integrity. Meanwhile, the space they are in has destroyed an entire crew of another ship and is affecting the Enterprise crew. Oh, yes, the Tholians, who are ticked because Spock fired phasers at them, are building a web to tie the Enterprise up for eternity. All these plot elements are interconnected and eventually come to a head. There were certainly some very good episodes in the third season and this is one of them. It's also intriguing how McCoy can be so cruel (almost racist) to Spock but never offers anything of any use to solve the problems. Of course, in this one he is suffering a bit of space sickness. Anyway, they are an interesting pair.
