on the verge of a massive supernova explosion and when we finally see it,

"We" won't see anything unless it has already happened and that...about 600 years ago.

And, I thought Betelgeuse was in its death throes much the same as our Sun will be at the end. A white/yellow average sun that has expanded to a red giant. I'm not certain what the history of BG is.

If the aliens around the star say Betelgeuse three times in a row it will explode.......
