Why are the potentials the same?

Could someone tell me why the potentials are the same in http://i.imgur.com/EdnqE.jpg.

I am talking about right under the part where it says "Also, the potentials across them are now the same, so that V = q/C gives". I understand everything prior to that. I even understand the stuff after it! I just need to justify to myself the theory behind why the potentials are equal so that I can move on. Please be elaborate but a short response is fine.

Any input would be greatly appreciated!
Thanks in advance!

They are connected in parallel so the potential is the same for both.

How do you discern that they are parallel? I was under the impression that "(b) After" is in series.

The positive terminal is connected to the positive terminal in both capacitors.
