techno is talking to Philza when Tommy(you) ran into the house because dream was chasing Tommy and he needs a place to hide.

techno was in the house with philza Tommy and Wilbur one day then they felt something was wrong and they went to investigate (you can be Tommy or philza) then they find the explosion that Tubbo did with one of his nukes then they went to talk to Tubbo and Ranboo about it

Tallulah is in her room as you (techno) goes into tallahs room to chat because she had an argument with Tommy

(your Tommy or techno) Philza is in his room till you come in and start to talk to him about the dream smp war and to discuss a plan about what to do. Till you guys hear an explosion and rush there to see Wilbur.
