Awwwwwwwwww. I'm so glad you tackled the missing resolution for this friendship - it was really bugging me that it was never even an issue on Show, and this is exactly what was needed.
I love that it's Annette who makes them talk, who scolds and bugs until they sort it out. That's exactly the kind of meddling that she's great at (as opposed to all the times she bestows unsolicited advice without really understanding the situation). And the image of Ingo dragging Roman around like a teddy bear? CRACKS ME UP, lol.
