Undoubtedly, the surprise call-up in Wales' 54-man World Cup training squad was tight-head prop Henry Thomas.
While left-field choices are usually expected in a Warren Gatland squad, the very nature of not being on the radar makes them hard to predict precisely.
But what made the Montpellier's selection fascinating wasn't just the fact this was a 31-year-old prop plying his trade out in France, but that he was also a seven-cap England international under Stuart Lancaster who actually played against Wales back in 2014.
Naturally, that raises a few eyebrows as to how he's now in a Wales squad. With a father hailing from Swansea, it's a simply a case of having served a three-year stand-down period since his last England cap against New Zealand in 2014 that has allowed him to switch allegiances.
But that might not have been the case had Eddie Jones not opted to end Thomas' fledgling Test career - with Thomas not making a single appearance under the Australian.

And, on a recent podcast appearance, it would appear that it was Thomas' unsure answer to one of Jones' trademark questions that might have cost him more caps for the country of his birth.
Speaking on Le French Rugby Podcast, Thomas said: "We had a full day of meetings, signing jerseys and kit fittings (when Jones first got the job). He wanted everyone to come in, speak one-on-one and he'd let you know where you were at.
"I was like, sweet. I built myself up for this meeting. I went in quite early, I was maybe third in there. Maybe too keen, I don't know.
"He said, 'Look, I see you as second-choice at the moment'. I was thinking that sounds really good, I'm really happy with that. He wanted me to work on this, this and this and said he had a few questions for me.
"The one was how the opposition loose-head I was playing against would describe me in three words. That's absolutely not me. I was thinking do I big myself up here, play it cool or act like a hard man?
"I honestly can't remember what I said, but it was obviously wrong because, the next day, before we'd had a session, they sent a load of guys back to the clubs and I was sent back. I didn't get a look-in for nine months or so.
"I skipped out of that room thinking 'spot on'. Second choice. Dan Cole was first-choice, he'd been there for a long time and was a very good experienced player. I was thinking I can build from this. Then I was gone!
"The question really wasn't what I was expecting from a new head coach if I'm honest.
"Maybe he wanted 'I don't care'. I've thought about this meeting a lot since. Should I have said I don't care what he says. He probably thought I was a little too posh and got me out of there."
Thomas admitted that wasn't the only "weird interaction" he had with the former England coach, with another phone call seemingly revealing how little attention Jones had been paying to the prop's club form.
"He once called me when I was injured," he added. "I was in Portugal on holiday after having another shoulder operation. He said 'Look, I'm really sorry as you've been playing really well, but we're not going to take you on the summer tour'.
"I said I've been injured for the last three months. He quickly hung up after saying 'Yeah, I know, but you were playing well before that'.
"You're never quite sure with him. I think he's testing people more than you think. His mind games are second to none."
