Was that a hint about .... (spoilers)
... them getting hooked up?
There has been speculations before that Max and Caroline might hook up by the end of the show.
Today at the end of the episode they were about to kiss when Caroline suddenly says "We're not there YET.". The YET is what might be interesting.
Also Oleg talks about them making out.
I personally believe it would be great if they eventually find out that they're made for each other.
