One heartwarming moment could be when Arthur defends Merlin from the other knights who are teasing him because he's his 'little brother'. Arthur might say something like 'He is my brother, and you will respect him as you do me'.

Also, during a big battle, Merlin might be in a tough spot, and Arthur charges in to rescue him, shouting 'He's my little brother!' which is a very powerful and heartwarming moment.
Merlin's magic can both strengthen and complicate their relationship. On one hand, his magic allows him to protect Arthur in ways others can't. For example, he can use magic to heal Arthur's wounds secretly. But on the other hand, Merlin has to hide his magic from Arthur in many fanfictions because of the laws against magic in Camelot. This secrecy can create tension, like when Arthur suspects something is different about Merlin but can't quite put his finger on it.
