Think about this: Faye knocked on a door which belongs to both Marten and Dora, but she only asked for Marten. Marten, or Faye, or both, could easily have given Dora a shake when Faye is panicking hard and talked it all out together--Dora -does- do comforting well when given the opportunity. Marten was in his room--he had pants handy, he could easily have pulled a pair on before walking out, though I understand why he didn't. Instead, Dora wakes up in the middle of the night to find her boyfriend gone, she walks out into the living room and sees him hugging a girl she knows he used to like.
To give an alternate perspective: Faye is freaking out and knows she needs to talk to someone. Faye knocks on the door belonging to both Marten and Dora knowing one, the other, or both will help her. Marten awakens by the knock, sleepily opens it, and sees Faye in full panic mode. Faye asks him to talk to her, he immediately says yes, and goes out to talk (in the living room, not Faye's room).
If Dora can sleepily wake up, go out of her room and immediately draw conclusions that may be influenced by her sleepy state, I see no reason why Marten couldn't also have done the same. Sure, his pants may have been handy, but he was sleepy and worried about a very panicked Faye. Sure, they both could have asked for Dora, but Faye just needed
someone to talk to (if it had been Dora who answered, I'm not sure they would have thought to wake up Marten either), and again, Marten was just focused on getting his obviously panicked friend calmed down.
I feel like the overall point is that, sure, lots of things could have been done, but no one was in a state to really do them. And really, it shouldn't have mattered. I agree with someone else who posted in here, that Dora makes every issue about herself, whether or not it is. Until she can recognize that, and work on that, she still will, and eventually it is going to alienate herself from everyone (I think).
Everything about her reaction in today's comic left me wondering if I'd really read everything correctly. Someone else posted that Dora hates herself so much/thinks herself unlovable that she'd rather push people away than be hurt by them (when her warped view sees them possibly hurting her). I think there's probably a lot of truth to that. I really hope that she realizes her extreme reaction to the situation is unwarranted, but I'm not sure that's something she can figure out by herself.
