|Headcanon 1: Punz & Dream|

I know for a fact that Dream was very open about getting Techno to train him when he was younger and was very excited when Techno agreed to train him and make the adults worry about what Techno would do to this child.
But when the Smp began, Punz was invited and Dream would say that Punz was very antisocial, cold and only was there for business and kept reminding people that they were not friends and it was just business.
But when he worked for Dream, Punz found themselves getting more curious about Dream seeing as the guy had so many tricks up his sleeves and his personality intrigued Punz, it also didn't help that Dream would always be talking to Punz and trying to have a conversation with Punz no matter what the mercenary tired to do that could signal Dream that they were not there to make friends.
Dream saw a lot of potential in Punz, despite the fact they was the child of the man that hurt so many people, so without Punz even realising it they grew attached to Dream and became more social with Dream and, Dream managed to convince Punz to let them trian them in combat, self-defence and even magic.
. . .
Punz still doesn't know how Dream managed to break them or even convince them to be Dream's pupil.
And doesn't understand why Boomer is constantly flirting with him.

|Headcanon 3: Jack & The OverSeers|

The OverSeers use Jack's body to either see what's happening on the server or to take control of a short period of time.
After they let Jack in control, he becomes dizzy and can barely remember what happened when his body was taken over.
Jack's opinions changed and were infected by The OverSeers without realising until he realised he was treating other members differently like Tommy and Karl.
Jack hasn't gotten use to having two people in his head/body but hasn't told anyone in fear.

|Headcanon 3: Sam Bucket & Sam|

Sam Bucket is an ancestor of Sam, before he would watch Sam with sadness seeing him play with Fran and remind him of his own dog.
Sam Bucket wanted to talk to Sam, but felt too scared to do so and wanted to help but sometimes Fran sees him and let's Sam Bucket pet him before he runs to find Sam.

|Headcanon 4: Wilbur & Techno|

Kristen took Wilbur back to their home land so he can be taught a lesson fir what he did and eventually take her place as Death.
Techno was called away to help Kestin involving Notch and The Wither Cult but he keeps in touch with Phil as often as he can.

|Headcanon 5: Quackity|

When Quackity met his end by Slime, he found himself reflecting on his actions and his memories.
He questioned why he did this all, was it worth it in the end and there was that realisation that all he did was made things worse.
Even if Dream deserved it, thinking back he made no difference in helping by starting a country, destroying Purpled's UFO and blackmailing Foolish.
. . .
So he agreed to give up.

|Headcanon 6: Ranboo|

Ramboo knows he doesn't have much time left, he knows it and is fully prepared to move on into his Limbo.
He's confident that Karl will help the smp and will be going back to The Other Side and hoped Tubbo and Aimsey forgives him for failing them.
