The problem with Dora was that despite Faye and Marten telling her repeatedly that nothing would ever happen between them, Dora still thought in the back of her mind that Marten wanted Faye, even though that ship sank and became a coral reef by 509.
"And if, sometime in the future, you happen to be ready for a relationship and I happen to be available..." - Marten
Hell, that quote was in the strip you just linked to! So Marten waited like he always does, and Dora swooped in to get him, but then resented the fact that he liked her friend instead of her at the time. That's not a story I'd want to tell in the future.
"Well, your dad liked my friend and was just waiting for her to be single, so I hit on him and he just went with it like he always does with everything!"
-"So, if the other girl had changed her mind he would have picked her over you?"
"Well, yes I suppose so..."
-"Oh. So you were just second best?"
"Um...."
Or even...
-"Why do you like Daddy?"
"Well, he's nice...and um...he supports me..."
-"So why does Daddy stay home everyday?"
"You know your dad, he never really liked any job that involved a lot of work, so he stays home to take care of you after school."
-"He's said today he's going to start up his band again!"
"Oh really...he didn't look for a job today?"
"No, he said he spent the most of the day at the pastry shop. I think he's going out with Steve tonight, can I go too? He said to ask you for permission!"
Where the fuck do people get the idea that alcohol is this all powerful truth serum?
Because, in most cases, it is an all-powerful truth serum. You say things you think but normally wouldn't say out loud. It also will make you hornier than usual. Combine the two and there are problems.
Rarely ever do we have a character monologue with himself. We don't know for 100% certainty that Marten had moved on completely just because he said so. In the past I thought I was over ex's and then, turns out I wasn't. Now that Faye is in a relationship we won't see Marten do anything but once she becomes single...
Alright, so Dora's had a string of bad relationships. Is that really therapy-worthy?
Do you have experience of bad relationships or therapy?
No, but I have enough experience to know that almost everyone on Earth would be in therapy if it was determined that failed relationships were needing of it. I don't advocate depression pills or therapy for a failed relationship for the same reason I don't suggest those things if you fall off a bicycle. It happens. It's life. Get back on and keep trying.
