I agree. Innocent local father man would be quite aware that it gets parky after darky so it's likely they would dress their Madeleine in something warmer than just pyjamas & with bare feet.
Also, why would you change into pyjama's at a creche before being carried home anyway?
Wouldn't you change into you're PJs once you were home at your own house?
Even if Smithman had been a local man visiting someone for the evening it still doesn't make sense carrying his daughter home in her PJs with no footwear does it?
Far more plausible surely that Smithman was either Gerry/ Abductor!
The abductor would simply snatch Maddie from her bed and leave ASAP, hence wearing PJs with no footwear!
Gerry would also dump Maddie in PJs without footwear, obviously to mimic an abduction!
Yes, I think it is more probable that Smithman was either Gerry or an abductor, and not a local resident!
Although, the Tanner sighting seemed to suggest a child in similar bedtime attire too!
Maybe kids dont wear shoes in Portugal?
