What about stuck in the ice! Like cryogenically frozen for at least 20 to 40 years however long and then finally they just melted because they were in prison with the ice and as because they're in prison now when they finally did get defrosted they were in prison
That’s my theory too! The AVL aren’t dumb enough to let the greatest villain of all time and her husband be in prison when people could break her out. So waiting years or decades before defrosting them means that they are still alive for Despicable Me 4 but won’t get help from other villains from their time since they were all old or captured.
In Minions, Scarlet and Herb were in their late 20s to early 30s in 1968. All 4 films of Despicable Me took place in the 2000s and Gru was in his 40s. Question, is it hard to age while you're frozen in ice?
Theory You know how if you are stuck in like a ice capsule you could like stay the same age well maybe she was in there for like quite a while and then just unfroze to the avl
Another theory what if scarlet while the minions were sleeping took some of there blood studied it and injected it into her own but it only makes her live way longer
