Lex, of course, was well aware of the fact that he had been followed. There wasn't much he could do about that, as his only power up at the moment was the kamikaze explosion.
Fortunately, his little maneuver paid off, as he climbed back on the track with a few seconds to spare. Moreover, the massive scorch marks where the cart in the lead had been targeted let Lex know he was on the right path. Only… there was no indication of the cart that had been targeted. Lex had to assume that whoever the driver was, Gerard most likely, had somehow survived.
All of them were driving the same cart? How had he even gained such a lead? Lex was genuinely curious now, and decided to watch a replay of the race after it was over. But it wasn't over yet.
