Grand Theft Auto 4: Part 85 Mr. and Mrs. Bellic - Walkthrough
This mission will occur regardless of which path you decided to take. However, we've covered it twice because the mission will go very differently depending on which path you chose. This particular brief rundown covers the "revenge" path, so if you just killed Dimitri on his cargo ship, then you're on the right path. You'll get a call from Kate after that mission is over. Since she's your date to Roman's wedding, you have to go pick her up at her place in Broker, on Savannah Avenue. After scooping her up, you can then drive to Algonquin, to the very same church where her brother's funeral was. The conversation you have with her en route to the church is an important one, and as you'll soon find out, it's one you'll want to pay close attention to.
