Kirk gets to the bridge and asks for an update. Spock says they are caught in fly-paper, an apt analogy. Given that communications are not being returned they have a few options. They can sit and wait for whoever put them in that trap, but they throw out that idea as it just shows weakness. This leaves them the options of destroying the cube or trying to get away from it. They decide to first try to get away, but it matches their every move and the radiation gets worse so they are forced to eventually destroy it. Kirk is not deterred and continues moving forward.
I've decided to remove intense debate and go back to the default blogger comments. Of course, ID holds your comment threads hostage so you will stay with it, but luckily I don't have too many. I have taken screenshots and edited them into the bottom of their posts so they won't be lost.
