Am I alone in thinking that this isn't over? Everyone, and most especially all the 'shipper tribes, are so quick to jump on the bandwagon of Marten and Dora are over, but I'm not so sure...
For one thing, they're at Sven's, and he hasn't made an appearance yet. Now, we all know Sven as a notorious womanizer. We also know that Sven is Dora's big brother, and that he thinks that Marten's the best thing that's ever happened to Dora. And he's had his own personal Jiminy Intern conscience working on him lately. He's been off the main stage for a while, which means he could have been getting up to all kinds of personal growth, which we got to see some of in his date with Hannelore. This would be a great opportunity to show us how far he's really come along.
I think that Sven is going to enter this little drama with something like 'Now just a damn minute, little sister.' What's more, I think this will lead into the Dora backstory that has been getting hinted at for such a long time; I think that will be the cliffhanger. Something along the lines of 'Just a damn minute. I've seen this starting to fray at the seams for a while now, and he is too good for you to lose just because you can't face your old wounds.' We'll hear Dora protesting, too, because she actually thinks they weren't that bad ('I've had... well, they weren't the BEST, but I was YOUNG...). She knows what Sven is referring to, and has been avoiding admitting the mistakes she made because she didn't think very highly of herself back then. I think the last panel will be something like 'Remember (one of Dora's boyfriends names)?'
The bell hasn't rung, kids. The fat lady hasn't sung.
In short, (Stars forgive me for this pun), I think Dora's going to have an intersvention.
