ARMADO: Boy, what sign is it when a man of great spirit grows melancholy?
Armado thinks Moth will say he's in love. Moping was the classic Elizabethan sign of loving. And calling Moth, "melancholy," Armado is hoping to get the man to admit that he is suffering from love. But Moth doesn't take the bait, so Armado has to wait to talk about it.

ARMADO: If drawing my sword against the humour of affection would deliver me from the reprobate thought of it, I would take Desire prisoner, and ransom him to any French courtier for a new-devis'd curtsy. (1.2.39)
Armado's a soldier. As a result of his military background, he might think that he can handle love with violence.

ARMADO: Adieu, valour; rust, rapier; be still, drum; for your manager is in love; yea, he loveth. (1.2.92)
At the end of this scene Armado develops beyond wanting to stab or ransom his love. He'll put down the weapons and write a love letter instead.
