Introductions Every introduction is different

[SandyPig]

Last night we introduced two new piggies. This is our 5th time with introductions and they never seem to go exactly the same way.

Piggie #1 has been with us only 2 or 3 months. She is a rescue pig that we took, to keep our older single pig company. They were great together but the other pig died a few weeks later

Piggie #1 has seemed lonely since then. She got more and more interactive with us, whistling for attention, and was obviously bored. So back to the rescue for Piggie #2 . Piggie #2 was living in a group and we felt guilty taking her away from her buddies. She was very subdued at first. The cages were next to each other for a few days and Piggie #1 seemed so eager to meet Piggie #2 .

It turns out Piggie #1 is completely intimidated! I don't know why. Their interactions seem normal for new cagemates, some rumblestrutting and teeth chattering, a little bit of nipping, some chasing. Nothing particularly aggressive. But Piggie #1 keeps trying to hide. She is spending most of her time up on a platform where a set of pellets and water bottle are.

Why is she so afraid? Anyone have a scared pig during introductions that eventually settled in and became friends?
