Do you have any info on 'Time Bomb' and the 'unknown v4' to the right of four eyed blues?

Time Bomb starts sitting on the ledge to the right of Innovator with a big undercling, then follows the faint arete and crack up and right over the block.

The unknown V4 on the otherside starts standing on the dirty face with a couple of crimps and moves up to the high jug before tackling the dirty top.
