"I'm shocked, SHOCKED, that there's GAMBLING in this establishment!!"
"Your winnings, sir."
"Oh, thank you."
As for what's going on:
It has been WEEKS since the break up, according to Marten in comic #1861. That could be anything from 14 days to two months, but the dialogue in 1861 suggests that Marten at least feels that enough time has passed that he should at least think about ladies other than Dora.
Also as someone pointed out, both Hanners's and Faye's hairstyles have changed.
It has still not been established in continuity that the girl with short hair and glasses to Padma's right in today's comic is in fact Renee, but it seems logical to make that assumption given what we have seen.
Now, in today's comic, Marten and Padma both seem excited to see each other. Whether this leads to a new romance remains to be seen, but...
And to everyone who says that a Marten/Padma thing can only end badly, I have to ask, Isn't that true of all relationships?
I mean if a relationship means anything at all, it's sad when it ends, and it will end eventually, either with a break up or a funeral.
