okay i was watching the round 6 again and i found this little detail
Till’s eyes dilated when Ivan cupped his face. Yet another hint that Till really did like Ivan - he just never realised it.
Pupil dilation occurs only when either the person is in a dark area, have consumed some drugs OR when they are looking at someone they like. They might also occur during adrenaline rush but im pretty sure the only cause that makes sense here is that Till liked it when Ivan cupped his face.
The fact that there’s so many little details in a 5 minute animation is both interesting and agonising.
