Hello! Actually your plant looks much better than it did in the previous photo. I guess with all the damaged leaves gone, it is good to see you still have some good ones left.
My Onc twinkle spikes once a year, usually during summer/fall (though this year, it spiked later and had just finished blooming last month). An easy way to tell is to look at the new growths. When they've swollen into new pbulbs, you should expect new spikes.
So it all depends on the new growths. However, since your plant has been through some tough time, it may not bloom for a year or so.
My Sharry Baby bloomed about a couple weeks earlier than my Twinkle, I believe. I guess there's no set rule for when they'll bloom--just give them bright light, fertilizer, and all that good stuff. I put mine on a west-facing window with some good sunlight.
