Ahem, I really liked what Shinohara put in here, so I'll share it with you.
When Sokollu Mehmed is talking to İbrahim, they show a fountain-like thingie. What is it? In Ottoman architecture, fountains are commonly used for practical and aesthetic reasons, but in places related to state affairs, they served another purpose too. The one we see in this chapter looks like the fountain in Murad III's privy chamber: https://live.staticflickr.com/7907/47184620241_1e06266db5_b.jpg
You should also look at the fountains on the window sills of the Sunnet Room in Topkapi Palace: https://www.canercangul.com/wp-content/uploads/2018/10/Topkap%C4%B1-Saray%C4%B1-S%C3%BCnnet-Odas%C4%B1-Pencereleri-1024x768.jpg
When you had running water in the room, eavesdroppers outside could not hear what you were saying inside. Instead, they heard the murmuring water. They are more effective when they are in front of the windows. For instance, the ones in the Sunnet (Circumcision) Room prevented the wailing of the princes from being heard outside
That's why İbrahim was angry at Mehmed, like the boy was being so loud that even the water sound could not suppress his voice and they could be overheard. That was such a nice detail imho.
Those fountains also served as ancient A/C, because water cooled the room on hot days. Win/win.
