Soon after their separation, paparazzi photos of Ferguson made front-page news in the British press.

To make matters worse, the duchess was vacationing with her in-laws at Balmoral when the photos hit newsstands.

Regardless, the damage was done.

When she returned to the royal estate, the experience was described as uncomfortable.

“[Philip] avoided her like the plague.

I don’t think they spoke a single word all week,” Ferguson’s friend informedExpressin 2005.

Philip reportedly tried to keep his and Ferguson’s Balmoral visits from overlapping at all.

If that plan didn’t work, Ferguson was given instructions to not interact or dine with him.

Despite the upheaval between Ferguson and Philip, Eugenie shared a tight bond with her grandfather.

In addition, Phillip’s situation had changed over the years.

He was 97 and no longer a working member of The Firm.

As a practice run, Philip and his daughter-in-law had both attended Prince Harry’s wedding months earlier.

After the ceremony, Eugenie and her new husband joined the royal family for a photo op.

Surprisingly, Ferguson was standing next to a seated Philip in the picture.

Some royal fans interpreted this positioning as an indication that Ferguson and Philip were on better terms once again.

Although, others asserted that they were just positioned based on their connection to the bride.
