I love this interview and had to clip these bits, featuring:
Seb being unable to pretend he doesn't know Kimi's bday and wanting to hear him say his but getting foiled by Brundle
Seb not-so-sneakily making it clear he'd like longer texts from Kimi
the famous (to ME) sequence of Brundle asking Kimi for Seb's strengths, with Seb looking down waiting to hear it, Kimi's answer of "not many off-days", Seb looking up like "not many of them??" and Kimi immediately clarifying it (they're married, your honour)
This is Spaceghost! So-called because he needed to be quickly and easily addressed as an emergent issue for those with the displeasure of meeting him. The device he created appears to anchor his consciousness (and part of his physical body) to an extradimensional superposition.
(Lore on the scene ripper under the cut)
The scene-ripper (a play on seam ripper, since the blade seems to be fashioned after one) can tear a hole in reality. It can alter the structure of a reality, or simply traverse through it to a more desirable universal position depending on the dexterity and control of the operator (so pilot dib).
He made the device while trapped in a nightmare dimension, as no one was there to help him escape it. It was more out of desperation. The scope was useless on its own; he needed to find a way to control the jumps... so he had to work with what he had at his disposal. Which was, luckily or unluckily, a world full of fucked up impossible technology.
He was trapped there for a long time, being hunted down and tortured intermittently while trying to engineer the scene ripper. His work was made easier by the fact he wasn't the only one wanting to leave. Most of the work was done for him, he just needed to understand it and apply it. And scavenge all the parts... and eventually use untested technology on himself.
Point of no return shit was easier to fall into than to step into. It was a lot like putting his arm in a nuclear generator surrounded by a bear trap. When he was able to check on the status of his arm, he found the matter of his hand to be inscrutable. There was a void where his wrist should have been visible on the underside of the gauntlet and a sharp blade manifesting from the darkness. He could no longer remove it... but it did work.
The scope itself also received upgrades more closely tying its functionality to the ripper and operator, but none so costly as that of the gauntlet.
