There trip North was rather safe for the first two days except the unusual noises at night, lewd ones, of course. The two women accompanying the men were actually selling themselves. Apparently, they were paid and were more than willing to sell their bodies for Red Spirit Stones so Lucy or Arthur didn't interfere.
Only the tall muscular man would remain by the couple's side at night, either rambling about his past achievements or trying to seduce Lucy, which didn't work for obvious reasons.
Although he didn't try to hide his lecherous gaze, he didn't try anything and despite hinting his intentions, he didn't voice his thoughts directly.
Lucy turned a deaf ear to him and followed the somewhat decent group without having to fight too much. Their traveling speed was slow, to say the least, however, that's only because the group wanted to hunt as many God beasts as possible and pick up some herbs.
