It gets complicated because we don't know how many buyers there were involved with the last transactions.

If it was just one that bought all of the 26 plus 10k of the next Ask of 33

or

If there were two people playing the stock at close.. one trying to drop it down to 26 and another trying to push it back up with a small 10k buy of 33

or

both sides were conceding at the last minute.

Either way, the trades were all in the 30's before the 26 spiked down suddenly, and then it was overbought and came back up.
