To be fair, the first time was a badly translated idiom. Either the translators or writers probably decided to just roll with it afterwards. Then again, the character itself may be some kind of autistic, seeing as at one point he honestly thought hiding under the covers would work.
It wasn't a badly translated idiom, it was followed up with "That's how things are supposed to be". The topic was related to Saber wanting to use the grail to change her past during the time she was alive.
Did you make it one word by accident, or did you mention me on purpose? On a different note, Fate/Kaleid's anime art gives me eye-cancer. They took the manga which looks like this, and made it into that ******* you see above.
If you mean Heaven's Feel, no, it doesn't happen in Kaleid. In fact, the 5th grail war in itself never happens in Fate/Kaleid. Fate/Kaleid's story is completely original (also, part 3, where the picture above is from, is by far the best, part 1 and 2 are trash in comparison)
I kinda like the first one in a way, especially if it was worded differently.
Kinda like a "It doesn't matter if you're correct, because that's ******** ." Never did like people using facts to justify immoral acts or invalidate moral ones.
