Well I was think of having Larimar has like an assistant to SunStone when they were a part of Homeword before joining the rebellion and so they I was thinking of during the gem war he went into.a force fusion to help defeat the homeworld gems which lead to shatter homeworld gems but also shattering some rebellion gems and then the unstable forced fusion ran off. So when Sunstone found them she unfused them and bubbled them both. So Larimar in simple terms would been like Bismuth and how she came into the action. Also Larimar after someone unbubbles him he would kinda be all clumsy kinda like how lapis was after she was taken out of the mirror. Idk this is all just from the top of my head
