here is the saucer to complete the set https://www.amazon.com/Fiesta-5-7-8-Inch-Saucer-Turquoise/dp/B0000CEP1A
If it's not clear from the OP, the AMA will be on /r/IAMA not here.
Also, this will be 10pm in the UK, 11pm in Central Europe. You can check this on websites like this one in the future, OP.
I checked the Amazon Spanish site: Amazon.es
It looks like the show is in English but perhaps the international version has more subs available? My Spanish is too rudimentary to tell from the description.
If you’re adventurous & tech-savvy, I found a website with subtitles in many languages: subscene.com
I’ve never used the site & would recommend using a VPN to download. Even then I suspect you’d need to download the episodes to link up the subs. (Disclaimer: Not recommending anything sketchy, just trying to help.)
It’s kind of you to do that for your parents. As my mom aged, she reverted back to her native Italian & enjoyed Italian films. Good luck!
Edit: fixed link
I downloaded some program called TunnelBear. I think it gives you free 500MB. I opened the site, and closed the tunnel -because it'd stream really slowly, and 500MB isn't that much- and it seems to be working for me. So connect, start streaming, close the TunnelBear, and it should be fine.
A long time ago I ripped seasons 1-5 OST from the website and organized it as a torrent: https://thepiratebay.org/torrent/9355384/The_Mentalist_Seasons_1-5_OST_by_Blake_Neely. I got nothing on seasons 6-7 though unfortunately.
You can find it here on amazon. There should be a saucer too. It's probably the same thing as your link, but just in case the other one is indeed sold out.
Okay, just checked. This is just from the Blake Neely score of the show (he did all of them). I am not sure you can find the name of that specific track but there is a soundtrack available. You can also listen to it on Spotify or Youtube or wherever, but as I say I don't know the exact cue for that riff (if this is where he is talking about noticing the scuffs on the shoes of the guy in the wheelchair.)
