Kousei & Kaori brawl-ish performance [Edited][Ep 04 of Shigatsu wa Kimi no Uso]

SPOILERS in the comments will be deleted. Only speculations and posts about the episode and the episodes before it are allowed here.

Kousai & Kaori are playing "Introduction and Rondo Capriccioso" composed by Camille Saint-Saëns for the virtuoso violinist Pablo de Sarasate.

For increased viewing pleasure some parts that doesn't show the duo and are likely to break the immersion were removed, namely:
1. Tsubaki's loud interruption.
2. Part of Ryouta's comment (accidently happened while cutting 1. out, but whatever, it won't be missed.)
3. The foreshadowing between the end of the performance and the beginning of the applause.
