Imagine Loki steals the Tesseract but it’s a fake, just a very very good one. In fact it’s so good it briefly fools Thanos, giving the Asgardians time to escape. Thanos then gifts it to Hela who is overjoyed…until she tries to use it. Once the truth comes out, Hela’s wrath falls on Thanos, solving a lot of problems for everybody else.
As for the real Tesseract, it’s on Sakkar, hidden in plain sight as part of the disco lighting.
