I agree with Fimber, but perhaps some plotholes could be explained:

Perhaps Merlin understands Arthur's position, because he blames himself for it. He considered himself responsible for Morgana and he could blame himself for Uther's death.

Perhaps Merlin's cold attitude towards Daegal was actually due to Dark Gwen. And maybe showing druid sign wasn't that suspicious - after all many people know him as Emrys and it's entirely possible that they told Daegal about Merlin(without explaining important things).

Perhaps Uther is hated because he started real war(Great Purge) on magic and/or achieved important victories. And/or perhaps, not being Sarrum, he was able to encourage anti-magical politics in other kingdoms(by negotiations).
