Rolf blinked in surprise, and then remembered that he was in the wrong place and he did have business to attend to. "Yes, you're quite right. Madam Mac an Ollaimh will be expecting me within the hour" he recalled "It's unusual for a portkey to malfunction like that, though. I wonder if we picked the wrong one by accident..." he spoke thoughtfully, half to himself, thinking that it was rather poor planning to have two portkeys going to different destinations left so close together. Not for a moment did he imagine that the woman might blame him for ending up here. After all, she had grabbed the portkey first, he had simply followed along because he assumed that she knew what she was doing.
Besides, blame was pointless. They were somewhere they hadn't meant to be, and now they needed to find their way back. But first, Rolf really wanted to know where they were so he could figure out where he would feel safe apparating to. "Perhaps we..." he began, but the young woman was now staring at something climbing out of the sea onto the rocks. "A lobster?" he asked, crossing to stand next to her. He only needed to stare down at the beast for a second before he knew what it was.
"No, no - that's no lobster!" he said excitedly, dropping to his knees and peering at it more closely "That's a mackled malaclaw. Don't touch it!" he cautioned, unnecessarily "They're quite beautiful, but their bite causes bad luck for up to a week and...I know where we are! You see, this one's a deeper share of grey than usual, an adaptation the stormy northern seas, and the green spots are more of a mottled pattern...We're somewhere north of Scotland...my guess would be the Orkney or Shetland Islands! Probably the Shetlands, this one really is quiet dark..." he clambered to his feet, positively grinning now.
"Do you have an apparation license? We should be quite safe getting back to the mainland from here" he said confidently. If the woman didn't - well, he hoped she wouldn't mind waiting here alone for a few minutes while he went to the mainland and fetched some help. It would certainly be more pleasant than getting splinched, which he felt would certainly happen if he tried side-along apparation for the first time.
