Just some words before I go back to my yearly socialisation with the family.
I don't believe the last stream was an intended pity party to gather pity money. DSP can't act or create future plans. It's way more believable he found himself in this emotional state and just ran with it out of poor desperation. Kinda hard being objective when you're in his situation, and be DSP. A late night talk with Kat may be the key. Really, horses never forget, including a Halloween stream, every mistake of him adds up. And when you think about it, when has DSP ever realized his own flaws? Only a girlfriend or Twitch can influence him, at least on the surface. However his performance was so damn miserable and awful, there is a small chance he might sensed it himself.
The throat pain arc: I will give him the benefit of the doubt as this is an easy explanation without corners. The timing also adds up, such a throat pain does not occur right after yelling or the next day, but when the vocal cords are in the middle of the healing process. Like muscle ache (in your throat), there is always this pain delay.
However. How hard is it to make a note on your screen: Sorry my throat hurts.
And speak with lowered volume if necessary. So I also estimate he might not have the enthusiasm after the garbage stream yesterday. Or he just lacks the imagination.
Dave won't move his ass or brain muscles if his house is in danger, his gin nights are way easier. His solution to the house situation will always be begging and blaming.
His lazyness, ego and lack of imagination will always be his big barriers.
