I'll put my speculation in spoilers. If you don't want to know or didn't want to look in the preview too closely I wouldn't look. Just seeing if anyone else thinks they saw the same thing.
Possible big spoiler
Looks like Jax shoots whoever meets Jax and Tig and not Tig himself.
But
Pope seems to always have countermeasures and a group of people with him, and he kinda is already on shaky ground with regards to the situation/hand-over because of how long Jax has been making him wait?
Gonna give myself an ulcer if I keep speculating, especially because I can really only remember two shots from the preview:
1: Tara crying
2: Jax pointing gun in Tig's general direction
