(this takes place after the movie but before future because at this time I don't know what happens during any of it after episode 8 so anyways let's get started to set the scene steven is at home garnet is on a mission with amethyst  pearl is home with him)

Stevens gem starts to glow

Steven: Pearl what's going on my gem it's glowing 

Pearl: What, do you know why

Steven: would I be asking you what's happening if I did

Pearl: I guess not 

Then suddenly a scroll appeared out of nowhere and his gem starts to rotate to the side to look like Pink Diamond 

Steven: PEARL COME HERE RIGHT NOW

Pearl:  walks in from another room

Pearl: what happened

Steven: This scroll appeared and my gem rotated 

Pearl: what well open the scroll, let's see what it says

Steven: ok let's see you will probably have to read it though I can't read gem gliff 

Steven opens the scroll and is surprised to see that it is written in English instead

Steven: wait what

Pearl: what is it

Steven: its in English 

Pearl: well read it then

Steven: ok let's see here

Steven: it says Dear steven, Shes not gone, Find her, find prism, find the only other one like you from: pink di- wait this can't be right

Pearl: why whos it from

Steven shows pearl the paper and points to the name 

Pearl: But how did she do that 

Steven: maybe when mom signed it maybe she just hid it and it appeared now

Pearl: no I would have known and how does that explain your gem rotating

Steven I don't know but more importantly whos prism

then a black portal opened up and outstepped a gem
