DEVIL'S NEST

in the scene where we see mepad laid out on the table, you can see what parts of him are damaged. mepad is based off the first gen ipad mini, and I think care was taken to make sure his internals were pretty accurate.

running under the assumption that mepad's construction matches a first gen ipad, i think it's a fair guess to say that the components that are damaged are the WIFI IC and the battery connector to the logic board (and the LCD and front glass but erm thats less important).

green - battery connector

orange - WIFI IC

obviously i'm not animation epic and i don't know how much thought they put into this, but my theory is this

mepad's WIFI IC obviously has a special appearance compared to a generic WIFI IC. my theory is that this could potentially be what allows him to teleport. i don't think mepad needs the WIFI IC to turn on, that would be on the damaged connector.

if this is the only damage mepad has sustained, I think its very possible to repair him. if they are unable to repair the WIFI IC, they could go without it or swap it for a generic one. either way in that case, he'd likely lose his teleportation abilities but i think that'd be the only real cost.

you can assume that meeple, like its real-life counterpart, is not known for repairability. i imagine that test tube has been figuring out everything without outside guidance, which is why she has been struggling with repairing mepad.
