Anyone call this strange all-in from a reckless player?

[Gramps]

The only note I have on UTG+1 is that, in a blind battle at the 15/30 level, she pushed all-in for 850 more chips from the SB with QJs. So...I know she's capable of making reckless plays. What I don't know is whether she's reckless with only marginal hands, or if she plays her big pairs the same way.

Are Jacks strong enough to call here (at this early stage of the tourney)? If not, what hands do people call this with given the read on UTG+1?
