Dialog 1 the eleventh hour [ 土壇場で ]

Angela:You drove around the US with your family for two months?
Yukio:Yeah! But I almost didn't go because I had a part-time job at a restaurant.
Angela:They wouldn't give you the time off?
Yukio:No, but at the eleventh hour they went out of business! The following week we were on the road!

Dialog 2 brush up on something [ やり直す ]

Angela:Wow, I hear you're going to Tanzania next week!
Yukio:Listen, I can speak Swahili, too! "Chikuwa kisu." That means "pick up the knife." And…um…well, that's all I remember.
Angela:That's it?! "Pick up the knife?"
Yukio:Yeah, you're right. I'd better brush up on my Swahili.
