20/10 ZG885 flying partner?

At 10:40 over Northampton this morning, I saw a Lynx flying North over Northampton. I was distracted by this and didn't realise there was a second military helicopter flying in the same direction a few seconds later, tracking slightly more East, until it was too late. It may have been another Lynx, but I can't be certain. I've found out that Lynx ZG885 was in the area around that time, but can anyone ID the helicopter it was flying with today? The callsign could be PILGRIM2 if it helps.

The second one was also an AH9. It was too far away from me to get an ID though.
