so far this trilogy seems to 3 arks, the gwen stacey stuff, peters parents and norman osborn dying
they are trying to come up with a serum to save osborn and obviously in the end it turns him into the goblin, so yeah its possible all these cross species stuff is a foreshadow to the goblins creation, remembering gene splicing may be part of what gave peter his spidey powers and thats gonna be linked to oscorp and his parents and judging by one of the pictures we see which was a diagram of a spider i think we may end up finding out what these spiders were
you may not like it, and you seem very much angry about the notion but all in all it connects quite alot of things together, connors creating a cross spieces serum in order to save osborn, norman becoming the gobling, his parents role in oscorp and the spiders and if webb wants to keep to that idea then yeah cross species rhino may lead peter into trying to find out whats going on at oscorp = parents,gobling,harry
a rhino tech suit links to nothing really
