From looking at Nitter, we can see that the xeet was posted at 6:48AM UTC+0 on March 31st. Due to Greece being 3 hours ahead, it was posted at 9:48AM UTC+3.
When setting Kiwi Farms to UTC+0, specifically Casablanca, as that's the region that's considered the most accurate, you can see that the post was made at 3:14PM UTC+0 on March 31st. Due to the time difference, it was posted at 6:14PM UTC+3.
Now, as we all know, he's quite a busy guy. As he (and correct me if I'm wrong, but I believe some of you) mentioned before, he has many tasks to do in his life.
These tasks can be anything, but, it could be possible that one of these tasks can be a job, or anything that would require someone to be gone for a while.
So what explains this 8 hour, 26 minute gap between the xeet and the post? My theory is that he was busy with work (after all, it was a Monday), and he either replied to the xeet before he got to work, or while he was at work. Sure, being on your phone at work is pretty stupid, but for a reply that small, it's possible he had an opportunity to reply to the xeet. But that still doesn't explain the 8 hour 26 minute gap in between both of them! And regarding that, I believe he made the Kiwi Farms post after work. It's fully possible that he works a typical 9-5 job, and it could take him an hour to go back to his house. However he could've gotten home earlier than 6, then he could've done a task for himself, such as making a meal, showering, etc., log onto the Farms, checked Blake's Xitter for any gemeralds, (these two events are interchangable), then make the post.
There's also another possiblity that he found the xeet by Blake while he was at work. In the following list of the account, you can see the same Kuweenmino that posted the xeet. It's fully possible that the xeet from Blake appeared on his feed while he was at work (it appeared due to him following Kuweenmino), he responded to it while at work, then posted on the Farms after he got back. However, you can see that he's in an incognito window (light theme and English despite previous screenshots from him being in dark mode and Greek), which means he's on a computer, and since Xitter doesn't sort xeets by newest to oldest unless you're logged in, that means that he had the link saved beforehand. With this, you can make a timeline of the xeet and the post.
1. He went to complete a task, most likely work.
2a. He found the xeet and posted a response. 2b. He found Blake's xeet and posted a response to the one he was quoting. During this, he saved the link to Blake's xeet.
3. He gets back from work, and does basic tasks.
4a. He looks through the quotes to the xeet, and notices one from Blake, which he opens in an incognito tab. 4b. He gets the saved xeet, and opens it in an incognito tab.
5. He makes the post.
